Are we perhaps complaining more than we are complimenting?

The only reason why I'm giving Afrihost a 3/5 review is because I don't know them and I wish to make a statement regarding ISPs. If one has to look at all the negative reviews and comments on all ISPs here on this site, we should be too scared to have internet at all today. Even my own ISP (which I don't want to mention on Afrihost's review page) which is nothing short of remarkable being with them for over 4yrs, is receiving too many negative reviews too in my opinion. The question to be raised is if we perhaps hear to many negative comments and too little positive, although the positive might override the negative? This could be due to people's nature to rather complain than to provide a compliment. Having said this, I don't ignore for one moment that people do have some legitimate and justified frustrations at times and taht they use Hellopeter to vent and voice their issues. Please let's also see more positive reviews too in order to ensure more objectivity?
