Buzz and Reader
So if you delete a Buzz thread that was shared through Google Reader, it unshares it on Reader. When you re-share it, it won’t be re-Buzzed, even if you want it to be. You also can’t make a Buzz that was private into a public one.
Add to these that my Twitter feed connection still isn’t working and that it’s looking like the Buzz feed will probably get unwieldy really quickly. This hasn’t been a smooth introduction to the service. Buzz needs work!
