Nathan can you please explain what the Icons are for in the bottom left corner of posts. Furl, technorati, del,icio.us, Digg. Thanks Mark
They appear to be for social media referrals, the far left one is for digg and one is for del.i.cious (or something like that). It's a way to, if you see a post that should be shared with the rest of the world, draw attention to that post or thread.
Moved to site feedback... I'll address this later, I need to learn more about these as well. Then i can write an informed article.
