The issue I have with it is that it’s hard to get your data out of the site once you start and redirecting spiders and Google to your new blog if you do escape is difficult to impossible. So for me it does not give you as many options as other blogging software and no plugin support but also if you move to your own domain, a hell of a lot of traffic will still go to the old site. Google “Twenty Major” and his old blogspot blog comes up 3rd or 4th in searches.
When it comes to business blogs it irks me a bit that Blogger/Blogspot gets all the linklove instead of the company even when they do decide to move the blogs to the main domain.
Cat pee. Is there an easy way to redirect with blogger/blogspot?
