wow, i just finished looking at your gallery and wow... im impressed, you have really great stuff here. I like what you wrote in your profile... I have the same problem :)... I lack motivation. Seeing other people who had the same problem and who are now improving is quite amazing... and it motivates me a bit too because it is very possible...
Subscribing to DA helped, since I can view the watched items as thumbnails. There was simply no way I could keep up with it all before, which is why I mostly stopped commenting until recently. Here, at least, we still have free thumbnails for our watches. That'll probably change as the community grows and eats more bandwidth.
If you're referring to the watches here, I think you can go to your "Watch" tab in the upper left and check or uncheck various things by each user name. Your friends will be displayed on your main page, but people you're just watching won't.
On DA, you can only display the friends box, I think, if you're subscribed.
