Why Start Blogging?

Today i decided that I would start a blog about my SharePoint experiences. Why? Even though I have never blogged anywhere about anything I have read hundreds of blogs and forums on SharePoint material and find it quite helpful. At the same time there are often problems I run into which I cannot find documented anywhere. So I decided that I should give a little back and not let my limited knowledge go to waste but share it in the hope that I might be able to help a fellow sharepointopian
