I heard that now WP.com is having a Posterous importer. This is
interesting, as Tumblr is much larger, and it also seems easy to
import Tumblr through its API (after all, Posterous can do it); but it
seems that WP.com has decided Posterous is a better target for their
importing efforts. Could it be that they perceive Posterous as somehow
more WP-like? Perhaps because it has fewer explicitly social features
(such as the reblogging thing) than Tumblr?
Anyhow, as of late, Tumblr has been rolling out feature after feature.
Admittedly, some of them are not very large, and some could be
designed better (IMHO), but they do seem to be designed with the needs
of the Tumblr audience in mind (to wit, the Formspring replacement).
Posterous has been relatively quiet in comparison, but I expect
they're planning some big stuff. Actually, there are some things I'd
like to see in Posterous:
a) When you login on the posterous.com main screen, the middle part of
the screen doesn't change. (Navigation options appear, but they're
rather small) It's still that posterous promotion material. I would
assume that most of the people logging in already are familiar w/ the
capacities of Posterous, so it just seems like a waste to not have the
screen change to some kind of dashboard, as Tumblr does. I'm not sure
what the ideal Posterous logged-in screen would be, but I would hope
it would be more useful.
b) Some kind of Directory or interest-finding algorithim. One thing
that Tumblr really does try to do is create ways of finding more
Tumblrs, in an organized fashion. They've tried several different ways
of doing this, with varying degrees of success. Right now there does
seem to be a kind of leaderboard system on Posterous, but the
organization there is fairly ambiguous. There's no sense about what
the recommended blogs are each about, or which ones would appeal to me
in particular.
c) Firefox plugin.The Javascript bookmarklet is well-done, but for
some reason runs slowly.
