If you don't believe in having a Twitter, here is a reason why you should. Yesterday...or two days ago (probably the later) I was on twitter when one of the people I follow who's the person who owns BelieveInFilm.com (#BelieveInFilm) retweeted a message a Kodak representative sent out looking for square format images. As that's one of my main formats, I replied to the representative with my website and Flickr account.
Today I'm the second picture on this blog. One of ten pictures.
There's a lot you can get from Twitter. If you're not on there, you're missing out.
