"If I were LinkedIn, I'd sell. Facebook is going to crush them."
Where's the intersection?
I like linkedin. I've had a few recruiters and business folks contact me through there. I'd be very reluctant to put my career stuff on fb. Perhaps some people mix business and pleasure?
I agree, I don't think most of the comparisons out there are apt, other than the fact the two companies are both at the center of IPO speculation in the valley.
Granted I'm still in college, but my Facebook profile and my LinkedIn profile are like night and day. I do put some of the information from LinkedIn on Facebook (they do have a Work & Education section in profiles), but that's not why people look at my profile.
I certainly wouldn't want the comments on my wall showing up when people are analyzing my profile as a job candidate.
The two services just don't mesh very well on a high level.
...yet. If all the college (and now graduate) students on Facebook start using the service as a recruiting tool, then I can see it being a real threat to LinkedIn.
You're probably correct that Facebook will have difficultly expanding their focus. So what. LinkedIn is still a broken product, and Facebook will continue gaining users just by doing their thing. If I were LinkedIn I'd be selling in a hurry.
