I'm also getting the following error, and can't find a solution anywhere online:
Warning: fsockopen() [function.fsockopen]: unable to connect to twitter.com:80 (Connection timed out) in [MYSITE]/wp-includes/class-snoopy.php on line 1142
I see it at the bottom of every page, even in the dashboard, and my site is incredibly slow - nothing will load until it's timed out, it seems.
My site is hosted on Dreamhost, I'm running WordPress 2.8.2 and have the lastest version of the plugin.
I've turned all my other plugins off for now and am still getting this error.
Any ideas, anyone?
