Came across asp-placeholder when running through some new questions. On the question I found it, it was completely inappropriate and I think the person was just picking tags until he'd used all 5... separate issue.
Right now there are only 16 questions currently tagged asp-placeholder, there is no tag-wiki, and I'm at a bit of a loss as to what purpose this tag serves. Not being a .net guy, is there some component or something I'm missing? Or is this a tag that needs to be addressed?
At the very least it seems a tag-wiki is in order with a definition and usage guidelines... I use those a lot when trying to figure out if the tag usage is appropriate.
