I suggest we kill this tag, it has no value without the wordpress.
The loop is a very important concept in wordpress programming, but not everything about wordpress is necessarily about the loop.
Every tag has its own importance, i respect your view. But every tag have its own reason for its making and sometimes tags are also used to clearify the question too.Its up to you which tag you want to choose for your question and which not.
If you don't need any specific tag that doesnot means that others users also don't need it.
And one more thing to say, differnt tags on the same topics are for making things more specific it will tell the users that the question is not only about
wordpress but also about
Its about being more specific about your question so there is no reason to delete that tag.
