advid.net's Journal: Slashdot survey: more suggestions

This survey about slashdot made me wrote some suggestions...

• A kind of Slashdotpedia: after an interesting question I gather the best slashdoter advices and my own search to make a journal entry. I suggest that I could back-link my journal from the article, even if archived. Then anybody browsing the article later could see that a guy has made a summary, a best of, enriched with his own work. Also those slashback summaries could be listed in a slashdotpedia section for great value added content (from a nerd point of view). See my three journal entries as an example.
  This mod is an easy one, few resource needed, work done by dedicated /.ers
• As a registered user I'd like to know which issues I've seen (loaded/clicked) and which articles also. Slashdot would need to keep a database of this, I guess you can't afford such a load. Benefit: I can read later just what I've missed, I don't need to keep track of read/unread items.
• I like those topic pics :) showing up along with articles, but we should see more often two pictures for an entry that could fit in several sections. I guess those new tags can help also.
• There's some space on the title bar that could be used for this:
  Display a kind of flag array (very small icons) to tell what is the mood of the discussion. Then we could at a glance see that they started (mainly) to joke / troll, or that they are serious with great feedback. It's a kind of automatic tagging but not for topics/content, only for mood/kind-of-answers/readers-behaviour.
