My recommendations for highly useful stuff on (& for) the Web:
- Google Talk translation bots are excellent for quick translations – just add the ones that help you most to your buddy list (actually, I find almost any service by Google highly useful, but won’t list all of them here…)
- ie4osx lets Mac users work with web sites written by lazy programmers (or lousy managers), not adhering to standards(i.e., working just with ie)
- MindMeister lets you collaborate on Mind-Maps with your colleagues or friends. Much more effective than traditional documents in yielding creativity & topsight
- Gliffy let’s you collaborate on diagrams with your colleagues or friends.
- Geni lets you collaborate on your geneologic tree with your family. It’s viral, it reminds you of b-days & just cool!
- Meebo lets you take with you all of your IM accounts on any machine that you go. It also has a widget you can use to talk to visitors in your site!
- Keepvid let’s you download movies from YouTube &c.
- daylight-savings-time.info let’s you see the time-zone differences around DST changes (OK, not that useful, but still here coz I wrote it! :-))
There are many more, but I prefer to keep it small.
