rather than make it offer other sites, I am writing separate plugins
for separate sites.
I already have a dreamwidth one written, as can be seen in my repo.
Can/maybe will write up insanejournal, deadjournal, blurty, etc.
eventually, too
required for LJ to know to which blog to post (since users
have posting permission to their own AND to community blogs).
It is now hardwired to their own, personal blog.
Eventually this should be more configurable.
Also, the plugin shouldn't be hardwired for livejournal,
but also allow dreamwidth, insanejournal, deadjournal, etc.
I'll work on that.
