I've worked from home remotely most of my carrer and I have actually spent quite a bit of time talking about hobbies with my coworkers. Even with my current coworkers, one of them is a tea afficionado and we have exchanged teas we like, one has similar taste in computer games (point and clicks) and we talk about this, another's husband has similar taste in novels and we have a semi unofficial book club and, finally, we have an actual book club within the company...

So, at least in my experience, socialising like this is entirely possible.
