Amen. The new endorsement feature is typically a sign of "how hard is this person looking for another job" which as a quality signal, may be inversely correlated with their capabilities.
LinkedIn seems to be expanding as a magnet for scummy and crappy recruiters. Awesome strategy guys. I love getting unsolicited phone calls from clueless strangers. At least I can ignore emails.
I think the business model for LinkedIn is to try and replace salesforce.com. Eg, maintain customer contacts on an interactive database.
The job search aspect is useful, but it needs work. targeted postings seems a lot less intrusive. the recruiter angle, selling premium access to my contact details is just obnoxious. gives us a good reason to shut down the profile.
