Everybody who has an LJ account, especially a paid account, needs to read this lj_biz entry. Spread the word, add your voice.
Here's my reply:
No thanks, I'm not interested in any corporate sponsorship on LJ. I have a paid account because Livejournal offers solid full-featured spam-free blogging with a large like-minded community. I will be happy to move my blogging elsewhere whenever I feel like it.
