I'm sure everyone would, or should, agree. Over the last several years it has been a constant problem, so much so, that the value of anything having to do with bonsai on the Internet has become devalued and under suspicion. It has gotten so bad that one is almost afraid to post anything lest some self justified grandiose wannabe bonsai master tears it down, and stomps it in the ground; not because they have a problem with the project but because they have a problem with you, generically speaking.
When I first started visiting the Internet bonsai forums about ten-twelve years ago it was a pretty friendly place, if not primitive. No one was posting pictures because the technology was not too user friendly. Eventually that changed, especially with the advancement in digital photography and subsequent soft ware. People enjoyed the company of others that grew bonsai and everyone offered to share advise and experiences. Then people started getting cocky thinking they knew everything and were not afraid to tell you so. From that point on the flame wars started.
Now it would seem, at least here, that tradition may have come to an end, thankfully. Greg seems to have identified it correctly in that of late the majority of the posts on this site are involved with other than bonsai issues and agendas of personal destruction. Civility has gone out the window and the single finger salute seems to be the pattern for the day. When we should be cultivating friendships we are instead, having to deal with adversaries. It seems that you cannot disagree with someone without it becoming personal, mean, nasty, long lasting and bitter. At this point it does not really matter a whole lot who started what with who and why, it only matters that it ends.
Today not too many people post pictures because you never know when some giant among many will call your stuff trash but strangely never post pictures of their own work claiming they have security issues to deal with. I think it is about time we stop acting like children and stop trying to make someone else appear small and Petty by being small and petty.
