The acquisition of Posterous by Twitter has been well publicised. I, like many others, suspect that this aquisition will the end of Posterous, though I sincerely hope not. In an ideal world, Twitter would make it even better.
I have a photoblog on Posterous (icraigt.posterous.com) and love the simplicity of posting to it and sharing (cross posting) from it.
However, I am in the same camp as @richardmackney on this one and have decided that I need to move the photoblog to a new platform in order to avoid the possible (inevitable?) closure of Posterous. Read Richards excellent post on moving his blog here.
I chose to move the photoblog to WordPress. Initially this will be hosted on WordPress.com (icraigt.wordpress.com) while I sort a new domain name (I was looking for an excuse to ditch craigt.eu and use icraigt.me), set up another WordPress install over on icraigt.com and import the photoblog. In fact the wordpress.com blog will remain (it’s a good backup).
Now I just need to figure out how to make all of the apps I use post to WordPress instead of Posterous (Instagram, Twitter apps etc).
