Related to this question-answer in meta.
The [photosite] tag seems sorted and has two questions tagged to it. Searching tags for "online" returns only [online-shopping]. Searching tags for "galler" returns two tags:
Photo-galleries tag has 13 questions of which 2 are about real-life physical galleries. Galleries tag has only one question, which is about a real-life physical gallery. The rest of questions (11 of them) are about online-galleries. Would it be serving any good purpose to have all online-gallery questions under one tag and real-life gallery questions under another tag? And have Tag-wikis to distinguish the difference for future questions tagging.
EDIT: One more issue - Gallery or Galleries? Which one looks better as a tag? There is now three questions under [galleries] and new one under [gallery].
