from a designers perspective I will tell you all that adding these types of effects and filters usually make me pass over the image, regardless of how good the rest of it is. I can add most of these things quite easily to an image, (without filters and the result is superior) but removing them is tough. That being said, I will only download things that are for the most part unaltered as they have more value to me. Also while on the subject of filters in PS, it is my experience that the best result a filter can achieve, is still substandard to the results that can be obtained in other ways, though they are not as easy to pull off. When I was in school we were actually forbidden to use filters on their own, lest they be used as a visual crutch to prop up a otherwise weak concept, image, or composition. Finally, I use PS every day for at least 3 to 8 hours min, for the last 8 years. If the filters don't do it for me, they probably don't appeal to many other designers that are worth their salt. There, that's my 2 cents!
