I need to warn the HN crowd. KreCi previously wrote an eBook on improving PageRank. There were a few good reviews and everything sounded great. He sold the site and the eBook on Flippa and make a few hundred bucks. Link to his blog post: http://www.kreci.net/blogging/pagerank-4-in-two-weeks/ http://www.kreci.net/blogging/pagerank-4-in-two-weeks/ Link to the ebook site (now owned by a Flippa purchaser): http://improve-pagerank.com/ http://improve-pagerank.com/ I ended up purchasing his book a week or so ago. It was quite terrible. The "secret" was e-mailing bloggers for back links. The book was probably about 10 pages, 9 pages were about how to set up a blog, buying a domain (with affiliate links), and then there was one page about e-mailing bloggers for backlinks, and a few example e-mails he sent. I can't say I expected much, but I'm afraid someone else might waste their money on this sort of thing. All this being said, I think KreCi's site is pretty interesting and there was some valuable/useful information there. I just feel a bit ripped off from the book purchase. I take it as a lesson learned, but hopefully no one else needs to learn the lesson here too.
