When I started posting photos about 15 months ago, a picture that I posted the day before could be seen still on the 2nd or 3rd page (12 or 15 to a page) the next day. Today four hours after posting a photo it is already on the 4th page. The number of postings have more than doubled, it seems. My point is this : I have the impression that unless you belong to a clique your photos won't be commented so much. Many newcomers post their photos but do not bother to comment on any photos. My latest posting has an 83% download but zero comments! So, must I send out requests for comment every time?
