The last names list. It’s not scaling well, and is probably the biggest sticking point for new users right now, prior to signing in the first time. At least, the people I’M trying to get to join. They want a good name and are willing to delay signing up till they can get one. There are a LOT of last names on the list now (over 300), and it takes a while to go through all of them. Many of them now seem to be geared towards a particular country or language – or at least, many of them are unpronounceable to me without working at it for a moment or two.
I like humorous names, myself, but was unable to find one that wasn’t taken after about 40-50 tries. It seems that some of the more generic English-style names have been on there for quite some time. Are they still being dropped after 100 or so uses?
