Do you find the time to write serious substantial posts in each one or end up abandoning one if you have 2+? I have too many interests to keep them all in one blog, but don't want to have a dozen blogs and lose control of them either. What's your best strategy for blogging?

BTW I paid for one of those 'review my site' blog entries today and you know what the person did, they copied and pasted a page from my site and called it a blog review - and they get at least $20 just for that! I think I got ripped off, not sure whether those 'paid to blog' servies are really genuine.

ouch on the rip xD
don't got any blog atm

Quite a few, but out of maintenance for variety of reasons.

I don't really know the real number, really! Only 4 really active at this moment.

I have more than 10 blogs but will increase later

i have much blog, but only 1 that still keep up to date. how lazy....

I had 2-3 blogs, at one time in 2007.
No independent blogs at the moment now.

I only maintain a small user blog at vbseo forums currently.

I have 4 blogs and I update them weekly 3 times. I want to create more blogs. Maybe in this summer I’m going to create more than 15 blogs hope I can take care of all of them.

I have 3 blogs. Two of them I update several times a week, the other one tends to get neglected, and I only update abount once a month.

I used to have 3, for battle.net updates in 3 games. But I abandoned all of those.

I think, if you're going to have that many blogs, you should make them either all on free sites, then make a master page, linking to them all. Or get your own site, free hosted or not free hosted, and just do the same, but you'll have much more control over it this way.
