I don't agree with you. I think, if people comunicate with others what they are doing, then that could bring a lot of mutual benefits. By knowing ones' profession, you could start building your own networking in your profession. You could share many useful information. I have seen people here in sajha sharing programming codes, exchanging legal suggestions, sharing new scientific advances, etc.etc. There is nothing harm unless you offend somebody by advertizing yourself though I am not sure if there is any way to offend others by advertizing self. However, we should not force anybody to tell about themselve if they chose not to do. It is all individuals' choice how he/she present among community. Some people may prefer low profile despite an extraordinary acomplishment, some others may prefer more exposure. If one tries to advertise beyond what he/she deserves, it will certainly backfire to him/herself, because his her peers are around to judge on his every activity. But if one decides not to tell anything about himself, he is decided to remain unnoticed. who cares whatever be his so called achievements.
