Excellent work done by yourself for humanity
Please contribute your more knowledge and share more open source software ….
I suggest also MyPaint, a very cool drawing application.
You could add a fine software installer.
Very easy installation of multiple programs with just a few clicks & no toolbars by default:

Several of these applications require the mono runtime be installed on your computer to run. Before you add that you might want to very sure the mono licenses meet your (and your boss’s if at work) needs.
Can’t use them here as mono is banned.
@Jesper: for Windows there is http://www.theopendisc.com/, for Linux you don’t need that, just use the normal package management/application installer (apt-get, yum, whatever).

I am posting this from my work laptop, running Ubuntu 10.10. I like FOSS and want to see it succeed.
On the other hand, be careful when you encounter lists of software like this. All is not as it may first appear. I don’t follow all of these projects, but Chandler and Handbrake have been silent since 2009. AFAIK, neither is experiencing heavy development and it is possible one or both may eventually die.
Before you download and become dependent on a piece of software — ANY SOFTWARE — Take the time to do the necessary research.
Don’t forget fotoxx!
Freeware is better quality IMO than “Open Source”.
Freeware does not matter on the type of copyright, authors, etc. It is functional – sometimes called crippleware, nagware, demo-ware & sometimes commercial (if commercial obligations are never enforced).
Opera internet browser is officially sometimes considered commercial, but for decades, I have never paid nor registered on any of my computers (including Symbian & Android).
The best ever “freeware” is not officially labelled as such: OPERA browser – most web-compatible, fast (not the fastest), spell-checker, inbuilt macros, downloader, ad-block, instant-save MHT files.
In the MHT (compressed, TOTAL web page, in ONE tidy file), it is the ONLY internet browser capable of instant storage.
Of ALL the internet browserss, it is the only one usable on every popular operating system: M$ Windows, OS-X, Linux, Android, Symbian, etc.

Have you ever considered using SSuite Office’s free software?
They have a whole bunch of free software titles that is free to download. 🙂
Their software also doesn’t need to run on Java or .NET, like MS Office and so many open source office suites, so it makes their software very small, efficient, and easy to use. 🙂

What about Photoscape – the simple to use photo and batch editor?
OpenOffice -> LibreOffice
Could you come up with a replacement for igoogle? Wouldn’t it be wonderful if you could do it so the gadgets work the way they do on igoogle? I think it would be fantastic to show Google that they’re making a mistake…

I’ll comment on a few of these:
I can’t recommend FreeMind as historically it had data integrity issues. Selecting one node may result in editing a completely different node than one had selected. Still, it is the standard for exporting and importing to other Mindmap tools. Personally, I’d recommend Xmind for a free mind mapping tool. It isn’t open source, but the interface is a lot easier to work with and it has less data integrity issues. I ended up not using Xmind and switched to standard note taking tools.
In the media group, love VLC as it supports so many codecs (depending how it is built)..still needs a bit of work on the encoding side (so I use FFMPEG for that with command line). That being said, while I liked Handbrake, it’s build system was nuts, so this is another reason why I use FFMPEG.
I don’t use the above movie editors, but I do use Kdenlive, which through one of the open source build systems makes a good cross platform for Mac as well (but I use it on Linux primarily).
Definitely recommend Audacity for audio editing. Great for adding/importing/exporting certain audio, not to be confused for a full studio tool, however.
Firefox and Konqueror have been my favorite browsers forever, and while Firefox does not have Flash support like say Chromium does, I still prefer it and its extensions, I’m a bit biased. I don’t use Konqueror as a web browser, but when combined with Dolphin, the KDE file manager, it makes a greaf fully featured file manager as it can open WebDAV, SFTP, SAMBA, FTP locations using KIoslaves. One can integrate its bookmarks with the terminal program “Konsole” as well, which is handy from an administrative perspective.
For Chat, I still lean towards Pidgin. I’ve used it for years, and it has so many protocols supported, not to mention it supports the idea of metacontact support where one can mix the same contact together from different protocols. Additionally, it supports IRC. The only other competing messenger I would recommend would be Franz, but essentially one is using Chromium libraries to present several chat protocol websites into one app.
On Financial, I would recommend GNUCash, although some behavior it has (auto completion of descriptions, etc) has gotten worse over the years.
On the office productivity, I switched to LibreOffice over OpenOffice. Similar code base, but I haven’t had a compelling reason to leave LibreOffice.
Definitely recommend Thunderbird as I’m able to have connectivity to Office365 with calender support working with it. Some older commercial plugins give calender access as well, but I can’t recommend it.
I can’t say I would recommend OpenProj, as it isn’t very intuitive and I was not able no navigate it well. That being said, I’m not strong on PM concepts.
I can’t say I would recommend KeePass, but rather, KeePassX for the same purpose. Make sure to use the 2.0 alpha branch which should be marked more in the beta arena as it hasn’t presented any problems after years of use.
I would also recommend MediaWiki as it is exceedingly extensible and makes a great wiki system. I prefer it over Dokuwiki.
Finally, to refer back to my previous note taking tools, I currently think Laverna is a decent tool. KeepNote and TagSpaces would be close contenders, but KeepNote does not appear to be maintained, and TagSpaces has a terrible tagging system. Main complaint with Laverna is it saves its data in one’s Chrome/chromium settings directory.
