This is slightly off-topic but I think my earlier comment may have been misunderstood a little... it is certainly not harsh and has nothing to do with people maximizing comments or them being tit-for-tat and reciprocal. It's just about pointless silence really!

This doesn't really happen much, but if I look at someone's gallery for the first time and I make a comment and maybe even make something a favourite. I would expect that person to at least acknowledge me for looking at their work in that way. Ignoring me completely suggests to me that they have no respect for me, my work, or their own work! Of course, some people may have problems so I don't judge them harshly or even immediately and I will often go back to their galleries again and again, simply because I like their stuff. If they continue to ignore me though... the silence irritates me and I start to wonder if there's anybody there - art for me is also about the artist.

No one posts work on this site to hear silence! So why do they expect to be able to sit back in silence... it's just plain dumb, in more ways than one.
