For reference, I undeleted and then closed the question so that people with lower reputation can view it.
I am initially inclined to say that no, it's not on topic for the site. From one of the questions on the scope shift, you outlined the following (Borrowed from Narusan):
If your question is about...
disease prevention and management
human physiology and pathophysiology
diagnostic and prognostic methods
… then this is the right place to ask.
For a lot of items, I try to have a litmus test question. In this case, it is "Will knowing this information advance my knowledge of medical science?", which in this case, is no. Just knowing where there are trade shows, and/or what trade shows exist, does not fit either the criteria listed, nor does it really fit my test question.
Additionally, this is a limited usefulness answer. Just because company A is hosting a trade show in a location this year, there is no guarantee that the same company will be hosting a trade show again the next year. Link only answers are pretty much verboten all over the SE network, and this is essentially asking for a list of links.
