2,5 years ago as I was experimenting with viral marketing on Youtube I decided to tape this video to understand the process. Badly recorded, done in one go, no editing.
The video viral success took me by surprise. In 3 months it was being used around the world by developers to convince management why they should use agile methodologies. The Agile Alliance and other sites linked to it.
I started getting some feedback and comments. I was shocked with the first negative comment I got: "What a load of crap!". It took me 3 hours to recover. I kept going back to it and thinking "why do this guy think this is crap? Maybe I could have done it better, etc"
And then I realized the following: in the Internet if you want to be relevant you are going to annoy people. And people have a fast, public way of annoying you back. I got used to it and I actually welcome it. And, as my mother would say, it builds character.
Besides my daily job as CEO of 
There are too many people without any sense of humor out there! :)
If you want to be an active participant on the web you definitely need to have thick skin, to take on comments from folks that in most cases are just having a bad day (to say the least).
Anyway, the best way to start an interesting discussion is to be provocative and "hurt" some feelings. Then the fun begins, but so do the relevant comments and contributions to the discussion.
