I've attended a couple of conferences, and just standalone public talks held at universities and I've found the topics interesting, so I've written a summary on my blog to share with others (and also as a way to help myself remember the content).
It just occurred to me that I'm potentially "stealing" someone else's IP. I always mention the name of the person / people giving the talk, so I'm not passing it off as my own research, but perhaps the presenter may not want this information shared via a channel other than their own. Some of them aren't just presentations, but may involve a panel of experts answering questions from a presenter / the audience.
What is the general etiquette when it comes to writing about this on my blog? Is it enough just to cite the author(s), or should I contact them beforehand and ask if they mind me writing about them?
(I don't know if it's relevant, but I get about 4 people a day reading my blog, so it's not famous or anything.)
