Hi, I was away from SEO for a couple of years. So a couple of years ago, blog farming was (kind of?) hot. I wasn't a member here but there were some good threads here about how to network your blogs, but everyone was very careful about not to be detected by the big G. Never do reciprocal links, only loosely link them etc. I had good results using rather aggressive blog farming myself (I personally made 50 blogs grouping into 5 groups, each had 10 which are tightly interlinked, and groups are loosely linked). It is actually still working well. Now I'm back to SEO, and I noticed the hot thing is (and maybe "was") join the blog network. So I'm wondering if what the big blog networks are doing is basically the same as blog farming (and the difference is we can join)? Is there any difference? That is my first question. Secondly, I want to know if there is a newest trend of interlinking your blogs. I know link pyramid and link wheel are hot, but it seems you don't really interlink your first/second tier. Is interlinking your blogs (or web.2.0 properties for that matter) getting a big no no? Every time I see information about link pyramid (and link wheel), it says not to link the sites in the same tier together. But if that's the case, it goes back to my first question. If blog networks are linking their blogs together, why can't we? (and when my old network is still working?) Sorry if it was a stupid question. But I'd appreciate it if someone kindly explain the differences and current trend and stuff. Thanks!
