Knitta - Tagging with Knitting. The general idea being to tag the neighbourhood with knitted pieces. Kinda cool - sorta makes me want to learn how to knit now...
So, I figured that since more and more people are starting to use Twitter, I figured that I'd let people know that, yes, I'm using Twitter as well, as a sort of occaisional status alert. So, if you want to know with slightly more regularity what's happening in my life, you can friend me, as kirby1024.
If you don't Twitter yet, you should probably at least check it out. It's kinda funky.
Basically a website that allows people to organise dates and meetings. Basically, set a number of possible dates, then invite people to enter in their availability.
Very specific tool, but a very funky way of doing it!
