Breakfast Topic: Guilded or unguilded?

Joining a guild can be a lot of fun, but it can also bring a lot of drama into your life. Some people eschew the complexities of guilded life and purposefully go guildless; others pick and choose guilds carefully, or bounce between guilds at will.

I've personally only found a couple of nice guilds in my time playing, and I generally don't join guilds with my alts on other servers--it's not exactly fair on the guild, since I'll not be playing much. However, I've found guilded life to be rewarding and (given the tales I have heard of other guilds) surprisingly hassle-free. What's your take on guilds? More trouble than they're worth, or worth their weight in gold?
