This may seem similar to the previous question I asked about the [dota] tag, but it's still something that I've pondered about.
I see quite a few questions around Arqade that relate to Steam tagged with [steam], and most of these relate to techincal issues with either Steam itself, or a game on the service that experiences an issue relating to the service or has certain Steam-exclusive features that are being mentioned in the question.
Now that's all fine and dandy. But sometimes, I see posts relating to a game on Steam tagged so... just because the game is on Steam. Even when there isn't any issue there relating to Steam nor is there any reason to tag it so since the problem has nothing to do with Steam.
Should doing so as mentioned be avoided?
