This is the type of question asked when someone really wants to ask a question (to try out the site, etc.), but doesn't have anything in mind. They pick upon something related and ask a vague discussion question. (Discussions are always easy to start, and we humans just love them – it's in our genes.)
Without more specifics, it should simply be closed.
For example, here's my brief attempts at specific questions about accessories, which are still on the discussion side, but have concrete issues that can be addressed:
Accessories for desert photography
I'm going to Burning Man soon and taking my [specific type of] camera. I'll be staying in a tent and only have room (in the carpooled van) to bring a 1'x2' camera bag. What accessories will be essential, and why?
What accessories will help protect my other gear from the desert environment?

Accessories for wedding photography
When doing professional wedding photography, what accessories are essential at the actual event? I've already planned out [some specific] shots which we did at a dedicated shoot. […]

I'm not actually asking these questions on the site because they aren't real questions for me, but more specific is better. Someone really needing an answer (rather than just starting an interesting discussion) should be able to elaborate considerably more.
