Please don't buy into the idea that you can write a worthwhile blog post about 'Web3' by telling us how confused you are. If that was my blog post I'd delete it.

(Simply by using the term 'Web3' in sequence with 'Web 2.0' and ignoring that the W3C was using the term 'Web 3.0' 10 years ago shows that you haven't been paying attention and don't have an informed opinion to share. Alternately you're qualified to be the annoying salesperson who points out the 'confusion' of anybody who walks into an audiophile store... Except for the fact that nobody has walked into an audiophile store for 20 years because we don't want to see that salesperson.)
