I'm taking on a background mission of deleting inappropriate [arduino](https://electronics.stackexchange.com/questions/tagged/arduino "show questions tagged 'arduino'") tags as they come in, like in [How to switch a Bluetooth module with a P-Channel MOSFET high-side switch?](https://electronics.stackexchange.com/q/157139/11684), which has absolutely nothing to do with Arduinos. The tag has become an absolutely meaningless [meta-tag](http://blog.stackoverflow.com/2010/08/the-death-of-meta-tags/), and really skews our statistics

Its interesting that this doesn't seem to happen with the microcontroller tag.

As an update, meta tags are officially discouraged:
