Thus far the Blogger + Pearltrees combo is doing what I want. While I've gone through a few different blogs and cloud based services, I unwittingly seem to be converging on an almost single login Google realm. I don't know if this good or bad, but it certainly has advantages.
But the question in my mind today is - what competes with the Google umbrella for services with a single login?
What does OpenID have for example? Are there other competitors? Only Google and OpenID come to mind?
Someone chime in here and give me some direction. Where do you blog? Does your blog service share a login with any other service?
