If I have a bone to pick w/ my friends, what's the best way to make my point, prove it, and share with them? All the political news that's been shared on Twitter, Facebook, etc. has been really helpful (or really scary to read).

What better way to prove a point with a friend -- cite + link articles, show stats, etc. Let's just say that during Election 2008, there was ALOT of heated arguments among my friends and ALOT of misinformation being spread out there.

I shared alot of http://FactCheck.org links on Facebook, etc.but FB only allows you to tag 1 photo/link at a time so you can't have a topic centered around, say 'healthcare' or 'immigration' or 'baseball'. I guess you can try Facebook Notes but it's not quite the same either.

That's kind of what I'm talking about. I hate having to email friends back-and-forth because I know some friends who hate being put on email lists. Facebook is good because everyone can monitor and anyone (in my network) can jump in and add a point -- but the only way you can share vids, photos, etc. is through Facebook Notes. 

Problem with that is if I don't want to have a debate with friends but with people in other places or fields. I'm not going to send FB invites to everyone...

Always show proof. Wikipedia? http://MediaMatters.org or http://FactCheck.org are great places to scoop out political issues and what politicians say vs what they actually do. Twitter is too short -- only 140 characters -- to have a developed argument (or debate) with a friend or stranger.

Agreed. I don't trust anonymous comments from websites -- you never know if people have an axe to grind against an issue.

That's why I think it's important to be able to trace people's comments, history so you can prevent being spammed.

I think http://digg.com is entertaining and filled with alot of churn -- there's alot of humor but also alot of good back-and-forth debate (aside from the pedo-bear jokes) with people actually linking and citing information. Often times, I find on Facebook alot of my friends don't join the debates because they don't want to rock the boat or offend folks (remember, some of us are linked to coworkers, students, etc). If you want to have serious debate, take it off FB and put it elsewhere.

The ability to merge your networks exists, although sometimes it is not very user friendly, however I think that organization is not really standardized on these social media platforms.  For example on social bookmarking sites like http://delicious.com/ people can organized links how they see fit, which is helpful to the individual but not to people who are digging through information.
