If you subscribe to Kukla's Korner with Bloglines, you may be noticing a delay in notification. This from Bloglines:
Bloglines is experiencing some slowing in posting new blog and news feed articles during busy blogging hours. This is a temporary issue -- we've simply outgrown our current facility. To fix it, we are moving our computer operations to a larger location that will give us plenty of room to grow. The slowdown doesn't put any user accounts or subscriptions at risk, and everything will be back to speedy once our move is complete. We apologize for the inconvenience, and thank you for your patience during this process.
