We just launched a WP Limits Twitter account. It will feature short (140 characters or less!) tips on WordPress or links to other great articles. Don’t worry, we won’t update more than once per day, so we won’t be spamming your account. Lots of great resources coming!
Make sure to follow the account here: http://twitter.com/wplimits
If you have any ideas to contribute we would greatly appreciate it as well!
