In Canada, the most left wing party is called the NDP. Some of their supporters have put together a very nice web site, with an extensive blog and diary section.
This is the main web site; http://www.rabble.ca/
and this is their 'diary' equivalent:
http://www.rabble.ca/babble/
You'll note that the diaries are broken up into sections, and don't drop off and disappear.
Obviously there are many more workers on that web site (it's actually the online edition of a published magazine), so I'm not suggesting Kos adopt the main web site.
I do think adopting the 'diary equivalent' is worth a look. The only downsides I can think of are
- somebody has to come up with all topic sections
- there are undoubtedly a lot more posters here than on that site, and we would jam the board. I don't quite know what would happen if that happened, though.
