Tumblr .... hosted for me (that's a pro, right?)That's a matter of personal preference. It's a closed-source hosted-only system, which reduces your ability to bend it to your will. It's customizable and extendable, but only as much as the owners choose to make it. Fine for lots of people. Not for others.
Is there a reason I should have an external blog on Word Press or Tumbir?
