Remove inactive links

Yup, removed those inactive links. Exchange link will improve our blog’s Google PageRank. The more incoming links, the higher PR that we will get. Of course, these incoming links must be from quality websites. Else Google will not like it. Same apply to outgoing links. Google does not like us to link to broken website (HTTP 404 error), illegal sites like gambling, porn, sexual related sites… Personally, I don’t like to link to unmaintained sites (those blogs that did not update for at least 3 months) and sites with no follow link in exchange. No PR juice will be given on no follow links. What is the point to have that incoming link?
