Yes I do. I don't own any forums my self either, although I guess I should consider one mine considering the owner is never there and I pay for everything lol.
However I do own a lot of websites I also help invest into a lot of websites as well!
Yes, I own and run a blog. Oddly enough my blog is about managing forums, and managing blogs. I write about all kinds of things from blogging tips, forum software, plugins, and everything else you can think of that is webmaster related.
I dabble in web-mastering, yes. I used to run around four different websites covering a varying amount of topics but slowly I lost the time and interest in running them. Now I stick to co-owning so that there is always someone else to motivate me to get up and get working. The best site I web-master with currently though is a technology news blog, it's going well.
