Another big problem on Wikipedia is people thinking they are overly important and list themselves on School and City articles as notable people. If you don't have a wikipedia article about yourself, then most likely you aren't notable.
The biggest problem with wikipedia edits are people NOT following the rules. People act like they can make CRAPPY edits in any way THEY like and then EXPECT those CRAPPY edits to stick. If you add a bunch of text WITHOUT a reference citation, then whine because someone deletes your text, then it is YOUR own fault for NOT adding a reference. Most people need to quit whining like a bunch of little girls and edit articles the correct way.
Grade inflation is why I ignore looking at GPA on an applicants resume. GPA isn't important, but what you have accomplished is important. I would rather hire someone without a college degee that is very sharp and has lots of experience than some college punk that hasn't done jack in the real world.
If you don't have to sign to recieve the letter (certified or registered mail), then don't contact them, because there is no proof that you actually received it.
If you find something wrong in Wikipedia then fix it, otherwise it is your lazyass fault for not fixing it.
Wikipedia is a great source to start learning about a topic and a good place to find references. An idiot would make Wikipedia their only and final source.
I've noticed that a very high percentage of new text that was later removed because the new text DID NOT have a citation reference. Don't whine because you are lazy.
If you really want to make contributions to Wikipedia and make them stick, then edit articles that few people are editing or haven't edited in a long time. Newbies should avoid articles that have a lot of current edit activity.
I can't believe they picked a PIC24F microcontroller. MIght have been better to pick an AVR for Arduino compatibility or even an ARM might have been a better choice.
