I have been suffered enough…from Blog.com! As a paid customer, my blog has been keeping down and down for days and there is no response from their support team. After recent 3-day down, I find my recent post is lost! So finally, Blog.com is beginning to get rid of customer’s post to get their overloaded server up again! Ridiculous? No, that is the truth. I spent the whole morning to export my blog from Blog.com and import it into WordPress.com. I have also paid $99 to promote my account there. Hope everything goes well here.
From now on, http://davejingtian.org is my new home and I will never ever update http://daveti.blog.com

I am having the same problem. I can not stand the fact that Blog.com is always down! They are owned by WordPress.com !
Really? Blog.com should be a standalone company as far as I can tell based on the About…
Anyway, WP is stable – so far so good:)
