When LJ went though its
grim staff purge at the start of January, WordPress made a post with instructions on how to import from LJ (
LiveJournal Migration Made Easy). After January ended, they observed that 7,111 blogs had been imported, despite the clunkiness of the process (
January Wrap Up). Apparently the demand inspired them to make a much better importer, comments included (
Even Easier LiveJournal Migration). Soon, those comments will even be threaded. WordPress.com does have ads, but they keep them as inobtrusive as possible, to the point where many people are under the mistaken impression WordPress.com is ad free. Additionally, the next version of WordPress will come with this importer fancy new importer, including mood and music custom fields, for those who prefer to self host.
In other news about places to move, and because I am a shill,
Dreamwidth entered closed beta last Saturday, and currently is shooting for open beta mid-April, depending on the amount of bugs testing turns up. It's planned to be ad-free.
At this point in time, the LJ clone InsaneJournal is still alive and holding steady at around 72452 active users a month, with 30902 monthly and 13265 weekly posters. The community aspect seems to be stable and sustaining; time will tell if the service itself will be. IJ is ad and paid user based.
