In general and right now i think it's a little spammy to have let's say more than 5 blogs, if you have 1 blog you can talk about the entire internet, politics and everything, why build 500 blogs for every word in the dictionary ?
I have about 6 blog but only 2 are maintained well. I do hope to maintain and develop the others this year.
I only have 2 blog and never had intention to add more because the more you have blog the more you'll have to maintain it.
I totally agree with that I currently have just one (the first one in my sig, the other is a friend of mine's) and will maintain just that for quite a while I think. I do have another four registered, but that's just cause one day I wanna start blogging about that topics too. The thing is that recently I don't even have time for the first one, so right now I think one is best
I have 2 blogs both in the same category although one is broad the other more narrow. want to add 1 or 2 more ... that is all i would be able ho handle
I have 2 blogs right now. One is a webmaster blog and other is a blog based on Entertainment niche so they don't overlap.
For me, it's not how many blogs you own for your blogs that matter most, but how much quality you have for your blogs. In term of quality and unique articles, popularity and updated contents for your blog..
