Not true.

LI is slightly useful for finding a job (at the expense of getting lots of recruiter spam). But it won't get you a job, and won't prevent you from getting a job. If it ever does prevent you from getting a job, trust me, you didn't want to work at that company anyway. (It's like companies that ask for your Facebook account and/or password. WTF?)

LI is also useful if you have no other web presence. But if you are a technology guy, what better way to say it than a custom domain name?

As a hiring manager, I find LinkedIn worse than useless for evaluating candidates. It's much simpler and easier to read their experience via their Resume compared the the kinda ugly LI formatting. Trying to glean info from their "connections" is useless, since many people connect at the drop of a hat. (i.e. being 2 links away from Bill Gates doesn't tell me anything about your coding ability.) The "recommendations" are also useless, because it's just one random internet user you don't trust vouching for another random internet user that you don't trust. Even the "skills" listing is broken: There is no "meaning" to +1 a skill, so people +1 skills they THINK their connections are good at and there's not objectivity to it.
