Dissenter is a variant form of web-browser that gives the ability to add comments to any website and so, make comments on twitter, wikipedia and I presume facebook.
The idea, is that when you go to a website, the browser displays the page, but it also provide an additional comment section for those with the dissenter browser. And this cn only be seen by those with the dissenter browser. So, unless you install and use the dissenter browser, you have asbolutely no idea what people are saying about a web page.
In practice, whilst I started by commenting on a few web pages which are notoriously dishonest, by far the most pages that people comment about are news sites like the Biased Corp (which long ago blocked any real discussion).
I think you may need to register through gab to be able to use dissenter. More of a problem is that all the big commercial browser are actively trying to block free speech so there are for example problems getting dissenter on a smart phone.
But, it is remarkably easy to use. In practice most comments that appear are about the latest news stories – predominantly in the US, but a substantial minority from the UK and a spattering of foreign languar from Sweden, Denmark and Germany.
For the first few days I did come across the odd racist or anti-semitic comment. But in these days of not only blatant but extremely manipulative censorship, seeing raw opinions free from the hand of censorship was a delight, although I quickly blocked them.
The result has been great. I’ve had one long conversation about the origin of fire (whether it was a drill or striking stones together). And several other quite esoteric discussions. It really does remind me of an old English pub where there would be a lot of men sitting down in a smoke filled haze talking about every subject under the sun without the slightest worry that the place will suddenly be raided by the Femi-stazis.
