What info brings to reader a thread post, which has no other info, but just one single word "#boom1me" ? Nothing. Close to zero.
Hence - I will be not upvoting such posts anymore

Yes, Sir. U r totally right.

Initially I thought the use of one tag Vs multiple tags

Yes, nothing #boom1me is just a tag with a chance to get your huge LEO upvotes. So that is the only reason to write just #boom1me. If anybody is doing that, you can tell that notheing else matters for him - wowowowow here comes big upvote.
