Speaking of bandwidth, I have a long question for you.
I'm running a self-hosted blog and I'm testing one at wordpress.com.
While I love the freedom of being able to manage and customize every aspect of the self-hosted blog, I'm a little bit tired of modifying things, and my main concern is the so called "unlimited bandwidth" that the hosting providers sell. We know that doesn't really exist, specially if you are on a $80 a year plan.
On the other hand, I need to start focusing on posting articles with images and videos for a non-commercial project, and stop expending long hours configuring, upgrading and worrying for service up-time.
Regarding bandwidth limits at WordPress.com, I'm aware of the policies that prevent abuse such as using a website to backup files, etc. But what would happen if I post a video (not embedded) an I get a million visitors (I wish) in one day? Would my WordPress.com blog survive to it?
