A quick note on usability

Am I the only one who doesn't necessarily always fill out online forms from top to bottom? The way some forms are designed makes it seem so.

For example, visit the free Basecamp account signup page. At the time of this blog post, if you fill in item 3 and then fill in item 2 with something different (and then click in a new field to have the change to item 2 "sink in"), what you have entered for item 3 is replaced.

There should be a check for this. I've seen this problem on other sites too. (Though it is kinda fun to pick on the, in my opinion, mostly well-designed Basecamp.)
