It's OK to be opinionated (I am) and it's OK to be proud of one's opinions (ditto) but the issue comes when we go into promotion mode, claiming everyone must share our opinions or be an idiot (I feel this way about some things, not others) and insisting that everyone needs to learn about the background for our opinions (likewise). In the particular situation when platforms are multiplying and the years behind us are littered with the corpses of failed initiatives that promised a world enough and time, the call to learn The One Best Technology becomes stale and annoying. It looks like an invitation to waste our time rather than becoming more expert with the technology we've already invested a lot of time in, and are just hoping we can make that time worthwhile before it becomes obsolete.
