(any modern OS) Instiki: Cool Wiki engine. Yet another stop along the road in my quest for the perfect personal task manager / to do list / project space. The notable things about this one: nicely self-contained (runs on its own included webserver), supports Markdown and Textile, runs on Ruby (Ruby built into OS X is too old, grab the prebuilt version that embeds the Ruby runtime or install a current Ruby dist via Darwinports or Fink).
(web) Memigo: A headline clipping service that learns what you like, can export feeds.
(mac) iEatBrainz: Uses the MusicBrains metadata engine to help you clean up your iTunes library’s metadata. Great for doing something about those “mystery tracks” that you collected from who knows where.
A friend of mine is into Voodoo Acupuncture. You don’t have to go.
You’ll just be walking down the street and… Ooohh, that’s much better.
