i don't feel you are being pompous at all. i've only been here for 2 days, but i'm already annoyed by people who do this. still, i understand how tough it is to start from scratch as many are just looking for ways to get more exposure.
but there are right better ways to do this, which don't make you look like an ass to the authors of the posts you are plugging on. at least read through their content and leave some feedback on it, and then if your own post is somehow related or relevant, then go ahead and share it. or at least try to build a connection first instead of going straight for the jugular.
thanks for the tips!
