I would really appreciate people giving a descriptive summary or introduction of links and videos they post. I don't go to unknown websites or click on just any link. I also don't know if I really want to spend the time watching or reading the item until I know what it's about. I remember idly going to one youtube link and it was a complete waste of time and I was left thinking I'll never get that 10 minutes back.

Is it possible to allow people to 'Endorse' posts? www.lion.com does this and I find it very useful. That way, if I am not checking up on the site every hour, I can sort through posts that have a high endoresement score. It would be very useful to allow readers to look up posts by this score because once they're just a few minutes old dpeending on how busy the site is, the post can disappear past the bottom of the 'most recent post' list.
Just a suggestion.
