11:45AM PDT: We are seeing issues sharing your posts and check-ins to Facebook and Flickr. We’re aware of the situation and working on a fix. Thank you for your patience as we resolve the issue as quickly as possible. 

Happy kiting!

Update: We’ve resolved issues posting to 3rd party sites. For those of you still having issues with Twitter, we’ve determined for users that signed up for Brighktite and added Twitter connect over 12 months ago were signed up using basic Twitter authentication (username+password). We’ve switched to Twitter Oauth which is much more secure. We did this a while ago even though Twitter still allowed basic authentication but the simple username+password combination was cut off today so anyone that added Twitter to Brightkite over 12 months ago will have a failure when pushing updates out.

To fix this, simply visit your account settings in Brightkite and remove then re-connect Twitter via the new Oauth method. That will resolve the issue.
