There is a growing trend amongst news websites to reduce or restrict the number of news articles that allow you, the reader, to comment on them directly on their site.
Many news sites are 'off-loading' discussion onto social media platforms like Facebook, Twitter and Tumblr citing the cost of moderation, legal issues and the general habit of people to be a little more vociferous when they are truly anonymous.
We don't have an issue with that, it's their site, it's up to them what they want do with it but maybe we're just a bit old fashioned and don't want to be flitting from one social site to another just to have a polite discussion with people we don't know who don't care about our opinions anyway, while all the time filling up our Facebook or Twitter accounts with comments about things our 'Friends' or 'Followers' really don't need a 'ba-ding' about.
So we had an idea, why don't we use Chrome's browser extension technology to make it look like your commenting right there on the site?
So we did.
Regarding moderation, we agree, it's way too expensive to pay people to pass judgement on everyone else's opinion and who is to say the moderators opinion is worth more than the commentors. So we decided that the best people to moderate the comments where the commenters themselves, so we've given everyone the ability to do their bit in moderating other people's comments.
