Same here - people that I haven't worked with but know socially have endorsed me for totally unrelated programming skills that were last used in the late 90s. LinkedIn suggests something, and people click Next-Next-Next. The whole endorsements thing is a joke.

Also not a big fan of LinkedIn's asking me to connect to the spouses of exes I haven't talked to, emailed, stalked, nor seen for 15 years and several email accounts. Massively creepy.
