I have some photos of a weed that I'm having trouble identifying. Is that a valid question?
If they're going to crop up and continue to weed about, we should at least edit the titles to be less than generic.
Here's a question title that's too vague and doesn't help external traffic:
What is this weed?
In fact, it probably doesn't help internal traffic when doing a search or browsing the site.
A great title gives you a heads up to what's ahead. Asking a vague question like the above gives none of that courtesy.
A better version could be something like:
Identifying a weed that has stocky roots, thorny stems and blue leaves
It does raise the problem of duplicates though; having lots of "what is this plant?" questions without any way for that to be especially useful as a long-term resource, with the same plants being asked about repeatedly. It's a limitation of the Stack Exchange software that it's almost impossible to search for a question by trying to find similar images.
In general, Stack Exchange sites are trying to build a searchable knowledge-base of expert information; these questions feel like they'd not be very easy to search though and won't add much value to the knowledge-base.
Plant identification feels like a very niché thing though. Maybe we don't mind as long as it's under a specific tag? I almost want to see a big library of thumbnails of differnt plant pictures so I could search them for one that looks like the plant I'm seeing.
I thought I would post a generic "how do you identify stuff?" question to head off these sorts of questions (and because I genuinely want to know). Gaming is full of "identify this game" questions and I'm pretty doubtful about their value to the site. Not to say I'm against "identify this plant", I just think we should keep them to a minimum if at all possible by referring people to general resources (if any exist). Plant identification seems like it should be easier than game identification.
