I have about 7, only 3 of which I actually bother updating. The others get barely any traffic so I don't bother with them. I have been concentrating on my blog lately because it seems to have attracted some readers!
So how many websites, blogs, forums, etc have you got right now? No free website providers such as Freewebs. Also not domains, full websites. Three websites, two blogs, and eight forums.
You can't own your client website ! Or .. maybe your a superhero ? I have 2 blogs + 1 website .. so .. that's 3 sites in total !
Just one, and I am more than happy with that. There was a time I owned three sites, and was an Administrator on another site, and a moderator in 3 other sites. That took up most of my time. Now I feel I am on a lighter steak.
That's a lot of websites... How can you manage your time and your 10k websites? Do you market all your sites?
