I think that sounds like a great idea. I work from home (which means I often go to work at the local library or Starbucks, just to get away from the isolation and to be in a more productive atmosphere). I also have joined a couple of meetups for the networking aspects. My main concern with the coworking space is the cost.
I like this idea, and have the same reservations @WebMachine. I know in my area, if I want to be close to home, there aren’t many coworking options. Most of those are limited on hours, so all times of the day is sadly not true, but the rest mostly is. Just not sure if I’d use a space enough to pay for one or not. I may try it sometime this year though, just to see.
