And My Axon
Limitations

I find it tricky to get full utility out of Tumblr. Partly because it’s blocked at work, so I can’t harness its networking features to share and/or aggregate interesting stuff. Partly because tumbling stuff from the iPhone app is awkward. Gack, as they sometimes say. Of course, I have a similar thing on Blogger, but it has dreadful iPhone support, with auto-jumps and text-resizing and general chaos.

No perfect scenario.
