The problem with tags for me is this,
If I knew what to look for I wouldn't need the tags..
If I have no clue what it is I am looking for, then how will I know what question to ask..?
Tags assume you have an idea what category of utility you are looking for and think on the same terms as the person who wrote the info file.. In reality those two are on opposite sides of the spectrum. The name I choose to search under has rarely been the description chosen by the author. For me tags need to be idiot proof.
I wish I knew how to improve upon the idea, but I'm scratching my head on this one..
Other than, please make it idiot proof
