Like books, personal blogs seem to have an innate ability built-in to the medium to bring out the best in people.
Do not confuse blogs with social media.
I have been keeping this list of my friends’ websites for several years now. Many are small business sites (pillars of society), none are vanity-driven, and all of the information is thoughtful, meaningful work by people who care. All of it is good. It represents the cream of 100+ years of electronic communication. That’s a strong statement and it’s true.
If you became literate and started reading books 500 years ago after the Gutenberg Press, you got ahead. If you understand the power the internet brings to people by enabling blogs, you get ahead.
