Probably not. Twitter, YouTube, News pages don't count as useful sources of information for me in the first place, already condensed for the format and expected attention span of the consumer. Summarizing even more seems redundant. I'd also wonder who was doing the summarizing. If I really want to learn something I have access to summaries and overviews written by people with expertise, and rated by other people: books. I may find those books, or excerpts from them, online. If you mean a summary of ephemeral content like tweets and online posts, I wouldn't have any use for that. I don't pay attention to most of that stuff now and I doubt I'm missing much.
