Hello there Miss K.O.......To answer your question, because I do happen to understand...
Some HP Staff ( or possibly all of them?) do write hubs. If you search a bit, you will find some. I'm sure they are much too busy running HP to write often, but I'm only guessing. HP is a huge operation to handle.
About certain people and their over-sized egos....(commonly referred to as Blow-Hards) those humorous characters can be found anywhere we wander. We can hardly escape them.
You obviously refer to HP egos. Once any hubber is here a while, reads a lot of hubs and interacts here & there, it's fairly easy to pick up on attitudes & personalities. There are numerous heavy-hitters here, some who have been here since the birth of HP. Most of them make a lot of money, know nearly everything about.....well, everything. As is often "typical," it all goes straight to their head......Like a formerly average guy who suddenly wears a uniform & a badge.
Now he's an "Authority," with the rules, a gun and a nasty attitude. Throwing their weight around has fulfilled every real thrill they never had. So, you understand this scenario. Basically they become real jerks in the eyes of everyone around them. They think they're exceptionally "cool." This is good because everyone deserves at least ONE fan.
It can be disappointing, but the good news is (as I'm sure you have found) the vast majority of all hubbers are as real, down to earth and wonderful as can be. I've made friends here and formed bonds that I will treasure forever. This is what makes it easy to ignore and disregard the blow hards...and those who worship them. They aren't worth time or effort. You will eventually not even notice them...as though they are invisible......despite the fact that they continue to snarl & snip at the peasants.
You are doing a fabulous job here and have reached high levels that so many simply don't. Smile....& keep knockin 'em dead, K.O !!
