It has been said that there is a fine line between obsession and insanity. To that, I would add, passion and anger and discussion and argument.
Perhaps here we can also add, this time a scale, appreciation and love. The latter being easier to write, I will use that. We either post or "lurk" because we have a love of photography. That would include form, colour, texture, lighting, pattern and composition (and perhaps, much more). Some of us also have a "love" of insects, flowers, etc. (Whether that extends to stacks of pencils, nuts and bolts and suchlike posted elswhere, I have my doubts but it would extend to e.g mineral crystals). Posting images, or discussing them, here helps to share and spread that love.
In such forums there are members whose first language is not English, so where would criticism of the language and grammer of submitted text start or stop? I find that typos are more frequent when I am excited, or have strong feelings, about the current issue. As a Brit, and an Englishman, I am aware that such forums tend to have American hosts and moderators so I have to respect the use of American English. (The forum would greatly benefit from a preview option before submitting a post).
What does upset me (not refering to this forum) is deliberate rudeness and inapproriate comments. An example of the latter was a recent experience elsewhere, where moderator (whether as personal opinion or not is irrelevant) was making comments, in replies to my topics, which amounted to technically incorrect or impractical and misleading suggestions for outdoor insect macro, having never posted any images of outdoor subject, while being prolific with studio shots. [Edit] The previous sentence should have qualified my objection: it is to remarks which would be taken to be expert and/or authoritative because of who posted them but there being little or no reason for them to be taken as such. [Edit ends].
