This isn't that much of a tip for those who know it, but I thought I'd state the obvious anyway. If you're starting up a new blog make sure you comment on other blogs alot. I just found another interesting new startup via a comment on my blog. This guys seems to be starting a mac game company, excellent!

Didn't I just post about the lack of games for the Mac? Excellent.
