[Plurkable - All Things Plurk] Plurk to UnVeil New Karma System at Plurkable - All Things Plurk: I know a lot of my mates (web developers and marketers) have had some grumbling relating to the Karma system (among other things, we’re a whiny bunch) - it is nice to see this is being addressed as the noise to signal ratio seems to be affected by this. As an algorithm nut, I shall be very interested in seeing what direction you take.

[Hacking the Good days...] Hacking the Good days”¦ :: The nature and challenges of community ...: So the end result is a pool of eligible users that represent (hopefully) average, positive slashdot contributors. Occasionally (well, every 30 minutes actually) the system checks the number of comments that have been posted, and gives a proportionate amount of eligible users “Tokens”.

[John Resig] John Resig - Google Groups is Dead: When we first started on LISTSERV, it was clear that spammers/malfactors spoofing subscribers or moderators email addresses was a future security issue, so we implemented self-moderation for moderators, while leaving self-moderation for the subscribers as an undisclosed tool in waiting. I still remember that day when one jerk thought he was going to post something using my email address, and all LISTSERV did was send it to me for approval.

[Tech Pedia] Digg Vs Slashdot - And the Winner is”¦ : Tech Pedia: (For example, a person browsing the comments at a threshold of 1 will not see comments with a score of ?1 or 0 but will see all others.) Moderators have been known to abuse the ability to increase or decrease the score of comments, and in some cases entire threads of comments have been marked down to ?1. Subsequently, a meta-moderation system was implemented to moderate the moderators and help contain abuses.

[taint.org: Justin Mason's Weblog] Blog Spam, and a 'nofollow' Post-Mortem / taint.org: Justin ...: Regarding the quote above from nofollow and the economics of linking, I find that attitude disgusting. People who see every human activity, even commenting on blogs, as a way for them to get a reward, and who arn’t comfortable doing anything without a reward should really reconsider the way they’re living life.

[Humanized Weblog] Humanized > Weblog: Battling Spam and the Ring of Gyges: There is a huge cost in deciphering (OCRing) images, no matter how simple they are, and I’m guessing most spam bots would not bother with it, especially if it is only for comment systems. Where they would try would be on services such as Gmail, where they can automatically get accounts (with manual setup of a bot to specifically target that web service), and use that to spam people who would not normally receive such and thus pay attention.

[LinuxInsider] Linux News: ECT News Exclusives: Slashdot Founder Rob Malda ...: Slashdot.org, founded in 1997 with the aim of delivering "News for nerds, stuff that matters," was one of the first Web sites to incorporate reader input in a significant way, and is widely considered one of the earliest precursors of the blog. With more than a quarter-million readers each day and about 80,000 articles, Slashdot is now probably one of the oldest exemplars of Web 2.0 -- Malda's comments notwithstanding.

[kuro5hin.org] Attacked from Within || kuro5hin.org: Reducing the number of full-time admins to do moderation reduces the proclivities toward the "iron law of bureaucracy" and toward user-moderation abuse. Like the above passive systems, a Robot9000++ could be set to identify general characteristics of comments that make them good or bad: not only originality, but also ideal length of the post (with diminishing returns after a certain point), presence of links, paragraph structure, and so on.

[Bad Science] Ten pieces of advice for old media - Bad Science: I do empathize with the frustration of websites that are slow to load and difficult to navigate (especially backwards), but for the first I think you actually need to put the blame on JavaScript and the for the latter poor programming in general. Flash is easily recognizable, so of all the sites out there that are poorly programmed, those written in Flash will stand out the most.

[Scobleizer] The chat room/forum problem (& an apology to @Technosailor): I forgot to mention that the karma system and friend/foe system on Slashdot also help users choose which people they want to read comments by, call it "soft" following/blocking. If you like someone's comments consistently, you can set them as a friend and give them (in your eyes) automatic moderation up so you are more likely to see what they say.

[Alice Hill's Real Tech News - Independent Tech] » Digg.com Is Silently Moderating Legitimate Submissions » Blog ...: yet you didn't see slashdot'er attacking digg.com when they came out. If there is a problem with shoutwire.com, let Keven and his gang at digg.com deal with them, don't flood the site with spam posts all using profanity.
