I have been asked to start a thread to discuss etiquette in the Critique Forum.
A while back when I first started reading threads and joining discussions on Typophile, the Critique Forum was one that had a large number of posters and replies, this was during the period when you could post an image with your comment and it was visible to all who visited that thread. This lead to Critiques which were inundated with images posted from all and sundry that deflected from the topic that the thread's creator had intended or desired*. So it was agreed (in this thread) that before anyone could post an image with their suggestion; permission was either sought from the thread's creator (or offered in the initial post by the thread's creator). There were many reasons presented for this, chief among them – to keep discussions on-topic, and therefore more helpful to the creator of the thread.
Circumstances have changed so is there a consensus for change, or should things remain as they were and if so should this information be offered in some way to posters of comments in the Critique Forums or indeed further afield.
My opinion is that it is more useful and supportive to the thread's creator to not post links to images of their work reworked or amended for two reasons
1. We can never have the full story behind the brief or concept (due to client confidentiality or time)
2. It shows a lack of respect to the thread's creator's work (because we can never devote the time and thought required)
There is a positive aspect too, that although we are basically image based in a professional sense, it is a useful skill to be able to verbalise your criticism.
The floor is now open to your opinions please feel free to link to images if you feel it will support your point of view.
*While this can be useful and provoking in a General Discussions thread.
