How come some photos get so many comments on Flickr? Do people just post them to a million groups and hope for the best? Some very very average photos seem to get so much credit...
If you invest the time to comment on other people's photos eventually many of them will return the favor. That's really the key. Personally, I don't have that kind of time. Comments are always nice but it can be a lot of work.
Hehehe... unfortunately you're right; I've seen that happen over there.
On a more positive note - if you participate in groups, that will get people to your photos. However you can't be thin-skinned. If you ask for people to critique your photos, you've got to be ready for a mix of comments. Some people give valid criticism (sometimes in a supportive way, sometimes in a harsh way), while others will just be jerks.
My friends flickr account has views over 1 Million. They do feature his wife in PVC gear though. Though I'm sure many view purely for the artist qualities of the images.
