Most stations in the US are now posting content transcribed directly to their own websites with clips of the appropriate story already. Promotion is the then directed to twitter/fb on an automatic or selective basis. Is this basically what you are talking about? In the scenario above, people find out about the content through search or directed discovery or one of the aforementioned social streams. If so, then please…
I am doing exactly what you said I should be doing "Perhaps a subscribable video playlist based on topics (like good alerts) not channels (like YouTube)". Could you be so kind as to just check my website and help me tweak my message.
