LinkedIn, as a site, at this point, is at best “weird,” if not downright user hostile. The problem with all of these web 3.0 businesses (because of capitalism in general) is that they keep growing until they absorb everything that touches on their core product, ruining the thing that made them interesting to begin with.
It would seem that someone could take up building what LinkedIn started out to be, before it became “Facebook, FOR BUSINESS!”, and then just let it run, to collect the money from recruiters, and leave it alone. Is it even possible to do? Is there no one who could build a lifestyle business on this idea, and not try to take over the world?
I suppose you’ll tell me that the network effects are already effectively preventing entry into the market, and anyone ruthless enough to punch through that barrier would, by nature, want to try to take over the world. And, even if they didn’t want to, eventually, if successful, someone would throw enough money at them to get them to part with it, and be absorbed by the Borg anyway.
