And then at the other end of the spectrum there's LinkedIn. Everybody is so relentlessly upbeat. God, I love a good pep talk as much as anybody, but half an hour on LinkedIn and I feel like I'm living inside a Successories poster.
True confessions: I do have a social media presence outside of LiveJournal (and its bearded Spock twin DreamWidth). I've got over 3,500 HIGHLY! MOTIVATED! linkies on LI, and I'm about maxed out on fb with 5,000 friends (and people I haven't gotten around to unfriending yet). Hey, I can post a cat meme with the best of 'em.
And LiveJournal? Well, I'm not sure if there *are* 5,000 people on LiveJournal. But it's about quality, not quantity!
