Some interesting links I’ve seen over the last few weeks.

• Twitter Click Research: What types of tweets get the most clicks? (via @danilolee)
• The half-life of a shared link is 3 hours on Twitter, Facebook, email or instant messaging…but twice that on Youtube.(via Mashable)
• YouTube Founders Aim to Revamp Delicious (NY Times) – I’ve used Delicious for years mainly as a cross-platform bookmarking service, not so much as a social link sharing service, but these days I mainly use XMarks. (via Techcitement)
• OAuth Needs Partial Authorization – as Alex King points out , many sites that let you log in using your Twitter, Facebook, or other accounts ask for too much access to your account. If I’m not going to use the service to post status updates, it shouldn’t require permission to post updates in my name.

On a related note, I’ve set up on Klout and PeerIndex, mainly out of curiosity. Their topic analysis needs a bit of work, though. Klout was convinced that my Speed Force accounts were influential about Washington, DC (rather than DC Comics) and, inexplicably, ducks. PeerIndex seems to think I post a lot about breakfast cereal.
