What keeps people away from blogging?

I was looking recently to our OPML list and I noticed that many people I know haven't started a blog. Or at least... not yet.

Which got me thinking: what are the most common reasons people don't start a blog? Is it too intimidating? Or it would be too time consuming? Or, maybe because it's something that looks too new, and most people are waiting for this blog fashion to go away before they really start a blog... I don't know, but I would love to see your comments.

At least in my case, my feeling was very similar with the one before jumping in the cold water. Not necessarily a bad move, but a hard to describe, restraining sensation that keeps you in not doing anything. Now I feel sorry that I haven't started my blog earlier... :-)

P.S. So, if you read this and don't have a blog yet, jump in.
