Regarding video content, but this kind of goes for other content too: Don't get in the habit of letting the content do the talking for you. Especially with videos, "you gotta see this" is not enough. Readers should be able to get ALL the salient points even if they don't watch the video. You can put it in a bullet list if you really have some aversion to writing complete sentences, but it all has to go in your post.
It's not part of the rules, but honestly just posting article after article "for discussion", with no input from you the poster, doesn't do much. If you think something is important, it'd be nice to know *why* you think that way. I'd much rather read a long post from a member talking about such-and-such topic, with an excerpt from the article (with link) as supporting evidence, rather than the whole article with a couple of sentences from the poster.
