Most bloggers are just want-to-be amatuer editorialists, who want to influence the public.
While I agree there are several blogs like this, most bloggers only occasionally embark on social commentary and usually it's just to get it off their chest. Like myself, they know that maybe a few or dozen people read their stuff and that most of them are either friends and/or the choir (as in "preaching to the choir"). Most of us do not expect our writings to be the key to social change. We're just expressing ourselves, like countless humans before us. The only difference is instead of doing it over a fence or in a barber shop or bar, we're doing it from the comfort of our own homes.
People post a lot of stupid, boring things no one else cares about.
Ego problem much? And where do you get off having the idea that everything on the Internet is supposed to cater to you and your needs? A lot of us who put up those "stupid, boring things" honestly don't want your readership. We're putting it up for our friends and family and for our own records and/or self-expression - and this is an easy way to do it. Don't like it - go back to playing World of Warcraft.
Everything looks the same.
Of course you're going to find a lot of similar stuff. We're all humans and have many similar needs and all that nonsense. You want mental stimulation, go to a library. They have these things there called "books" that are cleverly organized for locating interesting subjects with ease. Remember, the Dewey Decimal System is your friend. Learn its ways and the Universe is yours. If you want more mental stimulation, then enroll yourself into a class of something you've never studied before. If you want more than that, then you need to get off your tush and learn how to do valid reseach and start discovering your own stuff. Only you can exercise your mind.
You want emotional stimulation, go out and meet people. Better yet, become a volunteer. At the very least, call your relatives.
