Bloggers are blogging about the newest and latest mainly for marketing-purposes. If they're the first one to write about something, they might get more impressions and a better ranking, or even get on HN. It has nothing to do with the quality of the subject. There's too little time to learn shit on spec. I think it's useful to know what problem the new things solve, so you can learn it properly when it arrives.
Great perspective and thought. I see what you mean and agree with what you're saying.
Have a nice one!
