Depends, really. There's the good side of it and the bad side of it.
On a social context level, if you manage to fit in, then it's awesome. You'll make friends (some which will probably follow you for the rest of your life), you have a big degree of independence, and you can only rely on yourself to accomplish things (or have things done, which in essence allows you to maneuver through these things as you see fit). If you don't, though, it's not that bad either I guess. At least in my collegue, social outcasts weren't bullied or anything.
On educational level? Psh, it really depends. My college was trash. Most of the things I learned, I already knew (they just spin them to make them more difficult to understand and make people fail, but other than that...). Of those four years I spent on it, only one felt worthwhile, and a second one to a certain degree. There's also a forced "job-like" course that makes you work as in a real job, though you don't get money from it since the college itself pays it. It was a nice, since you get some laboral experience; if you already have it beforehand, it's pretty much pointless.
If you don't know what to do with your life, and have enough income on yourself (or a decent, not much time-consuming job), I think some years of college could give you a new perspective on your life, so I'd say go for it if you feel like. Also owning a degree in anything gives you the edge over the people.
