Just this morning I was bemoaning my lack of a simple todo list. I've played with most of the big names, RTM, Tadalist, etc. but this one looks, at least initially, to be much closer to what I need. I'm going to get my girlfriend / brain on it later hopefully to see if we can begin using it for coordination.

I love the plain text entry, reminds me of another of my favorite web apps, 30boxes.com. The calendar I use which manages my entire life :)
