At a startup I worked at, we were considering hiring a developer who was older than us (+20 years older), but in the end did not do it as we felt he might have trouble being managed by people significantly older than him. This was not my decision and I would have been in favor of hiring him - for the experience he could bring to the company.
Anyway, I now work in a team where most people (apart from 2) are older than me, and I consider that a priviledge. I get to learn from them in a great way, and I feel that I can teach them things as well. It goes both ways really.
And I do feel that in general here age is not such an important factor. Though that is just from looking at my colleagues, I am not in a comparable situation yet.
Just out of curiousity btw, does 'ff10' hold any relation to 'fast fingers'?
