Judging by the number of links in many of the signatures, I would say many users here are running more than one website
and some sites take less that an hour of your time each week to update (i.e blogs). btw i own about 10 sites.
But I think,without updating they cant list their sites it in the search engines.At least need some advertisements. Otherwise how did they get the traffic and making the money?
I have somewhere around 8-10 sites. Most of them take no time at all and run themselves, other suck up all of my time. But I enjoy it so I don't mind.
5, but more than 50 domains....a dn addict i guess... basically all failed development plans...hehehe
