I have some experience in this. For a few years not that long ago, I was in the news on a regular basis. Those of you from New York must've seen me on TV or in newspapers and I would bet a decent number would still recognize my name.
For the first half a year, I read every word about myself religiously. Every article, every comment under it, you name it. After a while, it starts to get to you. You also return to your normal lifestyle and suddenly realize you are too busy for this crap. You do check on it every now and again, but it's only the first few months of fame that you obsess about it.
As far as effecting a player's performance, I doubt it. Comments, both positive and negative, never made me act differently. Maybe you adjust a little about your presentation, but mostly you just forget what people wrote as soon as you are done reading it.
