This article is not that great. I think he means "drivel" instead of "dribble". I find that rants tend to be written in the "heat of the moment", and that copyediting suffers as a result. It would be good for the author to take a deep breath, re-read his writing, and trim it down a bit. It says the same thing over and over, and the "jokes" aren't funny.

It could even be trimmed down to a tweet: "Posterous is offering tools from migrating away from "dead platforms", but these dead platforms seem to have more users than Posterous!"

I also think that the graph is irrelevant. The graph only reflects the number of users with spyware installed. I have a feeling that Posterous appeals to more technical users than Tumblr does, and those users don't browse with tracking enabled. I use Posterous... and use privoxy and have my browser remove Google Analytics code. How many other users are like me? Probably more for Posterous than for Tumblr.

(I also don't post to Posterous from the web interface. I rarely visit my own "blog", although others probably do when I link to it.)

Anyway, choice is always good. Maybe the word "dying" is unnecessary in Posterous' ad copy, but they have a product to sell. Words aside, it's great to be able to get all your old content and bring it somewhere else. The other tools should allow importing from Posterous, and then people can switch back to Tumblr when they find that the grass isn't greener on Posterous' side. But the fact that Tumblr is behind with respect to data migration doesn't mean Posterous is "preposterous" or whatever. It just means they have a clue.
