Ask HN: How do you find experts at work?

[maith1]

When organisations get large and distributed how do you find experts at work? Either people who can help you with a problem or give you some advice? I find it hard enough knowing what the person in the same 50 person office is working on and what he could help me with.

Ah this is interesting, I often find it quite difficult theres company guilds where I try to network. But its hard to keep going to these when I'm always so busy. Often I look through github and org charts and try to work out who could potentially help me based on the code they've written but it's a bit of nightmare. I'd be interested to hear how other people do it. I know in some companies they have a skill matrix, but not sure how this scales.
