Facebook's up 23.4% to over 91 million users, and even shaky MySpace, which has seen declines of about 11% over the past year, got a 4% bump to 55.6 million users, and standoffish LinkedIn is up 13.1% to 12.7 million users. And the URL-shortening services crucial to microblogging are showing great gains too; tinyurl.com, is.gd and bit.ly are all up by double digits (21.6%, 21.8% and 48.8% respectively), with wee is.gd showing 3721% growth over the last twelve months.
