These are my links for December 28th through December 30th:

• It’s the end of TV as we know it – The Register's tech-focused view of broadcasters Project Canvas – which should demo at Easter and sell in summer (unless Sky/Murdoch succeed in fighting it and the BBC's involvement), this could herald the mainstreaming of IPTV (internet on-demand television delivered by web to computer or TV sets) which also leads to the end of broadcast TV (I think this will be a slow rather than immediate decline over several decades).
• Is the Tipping Point Toast? – Got sent this link by author Guy Kawasaki who believes 'nobodies are the new somebodies'. This is nearly a year old but a must-read article: it rebuffs Malcolm Gladwell's 'The Tipping Point' theory that marketeers need to target the influential, however, scientific research as shown that crowds are as easily influenced by each other as the supposedly influential, with connection between peers and friends more significant than the 'celeb Twitterers' etc. Important (if not depressing) lessons for social media marketeers.
• Social Media for Audience Development & Community Building – Very good article by video journalist Documentally giving examples of approaches and technologies for how a theatre production could use social media, and how it can be used as a means of communicating and collaborating with audiences.
