I tried to tag every post I’ve done so far and the tag cloud is getting bigger and bigger (check on the right side).
It somehow makes me happy, because the blog is not empty anymore.

Tag cloud is very important from what I read. It is the metadata of the page which google/yahoo etc.. reads to reference your  website to their search engine.
I don’t expect my website to make first page but I am sure that it’s a what most website admin are aiming for.
