Do we really need a tag for self upload?
It doesn't tell us anything about the actual contents of the picture, and I can't see why someone would ever want to use it for searching. The only other general tags* that I know of that don't have any bearing on the picture itself are the bad id, md5 mismatch and image sample tags - but at least they tell us that the artist has removed the picture, has changed the picture or actually made a bigger picture than the one shown on the site, which could actually be useful information for people who like the picture. Self upload just seems... pointless.
Tagging @kittey who seems to have heavily fleshed out this tag earlier today.
*edit: and the request tags, of course, but these also serve a purpose of being an easy way for taggers etc. to find images that want things adding.
