You say it's for lots of new features, but you have a tendency to
say updates are because of upcoming new features but those features rarely, if ever, show up. As someone stated earlier, remember when you guys updated the naming system so we couldn't have spaces or symbols in our usernames? You said it was because we were getting an email system, but that has yet to come out.
That was not the only reason, and we've already realized some of the reasons we made that change. e.g., if you want to go to a particular profile, for example, yours or mine:
http://www.gaiaonline.com/p/upcbetsy
http://www.gaiaonline.com/p/fleep
GIM required canonical naming like this to work.
It also simplifies storage and seeking in our databases, causes fewer cross-platform problems.
So yes, it's been useful and important.
