I don't believe the **number of close votes required** is working on low traffic and less popular tags.

* Fewer questions are read, therefore fewer close votes issued
* Less people have enough rep to close (by their 'low frequency' nature these tags don't generate much reputation for the users that follow them)
* Some people (even with enough rep) don't close questions anyway

Having said that, I can't think of a rule that can improve this situation that isn't subject to abuse. Anyone else seen this or have ideas?

**Edit:** I'm seeing this on the [Stack Overflow `sharepoint` tag](https://stackoverflow.com/tags/sharepoint). Here are examples over the last five days. Most of these have one close vote (mine):

**Edit 2: Is this what the `belongs-on...` tags should be used for? To alert other users with higher rep to close these questions?**
