It strongly depends on the company you [want to] work for - also depends on what you actually enjoy.

At a smaller companies go for breadth; there's only a few of you. Larger companies prefer depth - but! at larger companies there can be more projects for you to have your fingers in.

Depending on specialisation, work can be rare but more rewarding - but you can also paint yourself into a corner with things moving out of vogue. Silverlight/flash, Ruby, VB, etc.

I've been at it since the 90s. I'm a generalist, mastered a few areas, and worked in. It gives me choices - I where to go for a web-based job, I'd call myself a web developer and not boast no much about my C knowledge.

At my current job, most the skills I provide aren't necessarily rare, but the combination of them is - where it could take 2+ people to replace me (excluding productivity).

The balance is to specialise enough in a few areas, but not be a "jack of all trades; master of none"
