No, I feel a lot of people my age are not experienced enough to be able to write anything worthwhile. The result is "So I was reading this on [well-known blog] and here is my commentary", or "This is how you do X in Y", which should really be in the wiki for Y.
Not trying to be combative, but so what if they are?
My last (and widely viral) blog post was about me reacting to a blog post, but that didn't change the fact that many people found it interesting enough to forward on to their friends, post to Reddit, etc. I've learned so much from the reactions to my 3 short blog posts that I don't think I'll ever be "too busy" or "too inexperienced" to blog again in my life.
You must be the exception and congratulations on that. But surely we could all do without another junior-level-liberal-know-it-all-cause-I-keep-up-with-reddit/hn who will chime in on Google Buzz, Apple IPad, that dude who neglected his Markdown project, why Flash is dead, why Flash is not dead, why I switched to Django, why some language is the new hotness* , and beginner JQuery tips for good measure.
