I've thought about it. Eventually I suspect I might. There's a few reasons I'm not doing so right now though:

• I want the server we start with to be highly reliable, and that means I'd prefer to trust a host with more admin experience than I have.
• Self-hosting is a non-option for me right now in any case.
• While technically I could afford to pay hosting fees, I'm trying to spend as little as possible right now.

Eventually, I think I will want to set one up, just not soon unfortunately.
