Running your own server
Colin Walters says that running your own server isn't worth it, unless you have really specialized needs.
I was just thinking about getting a domain of my own, dusting off my old desktop and setting it up as a server for my email and website. Plus assorted revision control repositories for my toy projects, backups, etc.
I think I'll do it. Perhaps a year later I'll be able to tell if it was worth it.
