I HAD 4 at blogspot. I didn't do much after a slow start. Then they got googleized and stuff changed. I could not login because they wanted an email address in addition to password. Well, I couldn't get that info and couldn't reset the password. They simply never answered my support question on how to get back in. So I came here. I've set up 2 blogs here so far (one I post on and one I currently use for testing/learning and will post on later in about a month), and aim to make it at least 3 (somewhere to whine about stupid programmers in the world).
I'm also curious if it's OK to have a blog for each of my open source software development projects (e.g. posting just to announce releases, mostly).
