Why do people post Tweets and not the article itself?

19. It seems to be acceptable behavior on other forums

I share your annoyance with the DUers who don't take the time to describe or explain the video they are posting. Also people who post a tweet without even copy/pasting the text of the tweet. That's just rude because many people on DU can't see what's in the tweet, their security settings won't allow it. It's also lazy and inconsiderate for posters to do that.

However I've spent some time on Reddit, and perhaps a few other forums where posting in that manner is accepted. On Imgur there are no tweets allowed with live links, however people seem to post screenshots of tweets pretty regularly.

I hope DU makes a rule that live tweets won't be allowed in the near future. Posters will need to click through to the original material - it's almost always available somewhere outside of Twitter.
