Wait, a coworking center is a place you share with people who aren't your actual coworkers because you wanted to work remotely? Man, this new economy is out of sync.
I get that you're being flippant, but yeah, it does sound a little strange at first blush: work remotely, but without working from home?
The secret is that spending all your time alone actually sucks for a lot of people (and for those whom it doesn't, great! Working from home may serve you well).
It so happens that coworking strikes a good balance for many of us. My location and that of my employer are fully decoupled, and my coworkers don't have any overlapping office politics. When I change jobs, I don't stop seeing my friends. It's pretty ideal.
