Yesterday the oeis tag was created for this question about an oeis sequence. I assume that this tag would be used in the future for other oeis sequence questions (There was no usage guide or description until I added one simply linking to oeis.org).
Every question about an oeis sequence will most obviously also be tagged with the sequence sequence tag is it really worth having an oeis tag?
On the other hand this tag could be used to mark questions that are about the oeis rather than a specific sequence such as this one. However I could not find any other questions like that and it seems that, of the one question already tagged oeis, it is not being used like that at current.
