An article in Reuters discusses the natural cycle of self-esteem which peaks in childhood and mid-life and ebbs in adolescence and old age.

Here is an article that pronounces the death of metatags. I think it's a testament to how document design and real life can collide in ways that don't always work out. Metatags were an excellent idea, but poor or illegitimate usage have made them useless. As the author points out, search heavyweight Google doesn't even consider metatags in its ranking system. Sigh.
