Massey, I understood what you meant and it was my question, thanks. Don't go letting yourself get trolled now!
There is more to SEO than link juice, and to say those links in signature has NO affect is just incorrect. They will have some affect, just negligible. Indeed if they had no affect then why would they cause a search engine to crawl his specified site?
It all depends on how you use them and the context the links are placed in. Linking to the birmingham site as he does yet writing about SEO and business and PPC of course his links will have no effect as they are not relevant to the target site. Also he has over a 1,000 posts and if google crawls this site then they will see a 1,000 links going to an unrelated site and will consider them spam.
Now if you were writing articles on here, say in the finance section about finance and linked to a finance website are you really trying to tell me they would have no affect? Granted your not going to jump to page 1, not with one group of links from one website. If only life were that easy.
Why do people do directory submissions, why do people add themselves to delicious, stumbleupon, digg, reddit. To get backlinks.
Or are you claiming this site has zero authority and is known to be a bad neighbour?
Feel free to disagree with me, but don't call me a troll because you don't like my opinion.
