I am relatively new to Android so I don't know if this has been debated to death. I have seen quite a few apps reviewed in the Market where people (1) bash the app in a really negative way and (2) endorse a competing app. IMO, this is bad for the Android community. I doubt many of the people here do this but, anyhow, on a soapbox for a minute... First, it's a little like spamming up someone else's web page. Also... it just irks me because I would equate it to the Pepsi distributor walking into the store and plastering Coke displays with Pepsi coupons. It isn't fair play if it's done by a competitor. Second, even if it's not done by a competitor, I don't think it serves any valuable purpose. We have other ways to get app recommendations, including AndroidForums.com, and to compare and contrast apps. Hell, create a posterous blog if you want to do comparison app reviews. Third, apps often go through many iterations before they're satisfactory to the developer. Maybe some app doesn't measure up to your favorite but the Market is a poor outlet for that opinion; it's just plain rude to the developer who probably invested a substantial amount of time and money into making the app. I dunno.. I rarely get preachy but these negative + promote another app reviews bother me.
