Ah, Overread, you are still thinking of me. I feel quite honoured.
Yes, there was a time when I really gave a huge amount of time to commenting on many different threads, mostly so those that went by 0 replies, as I know the sad feeling you get out of trying to communicate with people (here via an internet forum), and no one talks to you. Whether that be some real criticism about what photo you posted, or just some general comment on that you've been to the same place, seen the same subject (for example) ... it wasn't always artistic, technical or other such aspects that came to mind when I looked at a very average photo.
But (!) that was VERY time consuming, and my interests also shifted a little (thing is I myself feel quite bad about my own photography and have felt like that for over a year now), and I felt I was saying the same things over and over and over again, so I sort of "left" TPF for quite some time, and now I'm only in the vague beginning of getting myself acquainted with the many, many, MANY new members who have meanwhile joined (and keep joining) the forums in droves.
