Should I always create new blogs or feed the already registered ones?

I always read that I should create blogs with links to my money site and blast these blogs with xrumer.

Is it ueful to create 100s or thousands of new blogs with one article or is it better to register 100 blogs that I always feed with new fresh content?

good question...

I think (could be wrong) is you want quantity here... so keep making as many links as possible.

On the other hand a few sites with consistent feeding might produce a more quality link for your site

i know...this is why i'm asking...

nobody has an idea?

the problem was already described: with senukex i'm able to register 100s or 1000s of different blogs. i put one text to them and ping and blast them with comments/links.

but is it useful to open always new blogs? wouldn't it be better to create only let's say 100 blogs and feed them over and over again to get these blogs to a higher pagerank and to more trust?

thanks for your answers!
