A lot has changed since the last time we took a serious look at blogging. A few items, as examples.
- When RSS came along Markdown didn't exist. The two technologies belong together, imho.
- Websockets have replaced long polling.
- Servers got cheap! (and easy to deploy).
- SQL is fast and the tools are much better.
- The user interfaces of all the Web 2.0+ products didn't exist last time we created new blogging communities. We can borrow ideas from twitter-like systems, even huge products like Facebook and Spotify have innovations that come long after the initial wave of blogging.
But one thing stays the same -- all the components are replaceable. Absolutely zero lock-in. We use simple standard APIs where they exist, and create new minimal formats and protocols where they don't.
Blogging has a simple philosophy that remains constant.
