Today and yesterday there were a considerable number of suggested edits
to previously empty tag wikis and tag wiki excerpts (see [here][1];
viewing the full list requires >=10K points, I think), all by the same user. 
These edits mostly didn't really follow the [guidelines on writing good tag
wikis][2], in particular they often didn't make clear which questions should
have the particular tag. On the other hand, having a tag wiki may be 
considered better than having no tag wiki, at least unless the contents
are too unreasonable.
It happens that these tag wiki edits were accepted by some users (like
myself, at least in most cases -- though I don't know whether this was
the 'right' choice), and rejected by others. -- Any opinions?
