The jury is still out. Google+ offers a larger platform for writing with all the benefits of twittery following with its' "Circles" feature. However, G+ doesn't (yet) offer things like tagging, or some equivalent to hashtags. Also, word is out that Google is planning some major integration changes between blogger and G+, so not sure investing the time here will be worth it.
In the meantime, I'll probably post tech-related content on G+ and cross-post it here until the G+/Blogger integration becomes more clear.
