... i'm devastated looking at some articles and their use of the concept of "tag".
Tags are to.. order things, to easily find what you need and create groups of similar objects. But internuts often get bedazzled and not only "don't" choose the best/most suggestive use of tags, but go for stupid ones.
Like.. let's say you were writing 20 stories about bears. The most useful tag that should unite those in a blog of about 2000 posts is "bear" or ... "stories on bear", "abearations" -or something similar.
But no. Looking at blogs i see tags like - one story has "Martin" [as a name of the main bear], one has "brown bear", one "Jimmy" and so on. That means 20 tags. ... Not smart.
Or i see something like 13 stories tagged "bear", 4 tagged "baer", 2 tagged "bears", "critters of the bear type" or something like it. It's a computer, numbnut :P It won't see that "bear" and "bears" are the same [...yet]. You end up with a list of 5 tags.
Duuh.
