What Is Gemini?

From Project Gemini:

Gemini is a new, collaboratively designed internet protocol, which explores the space inbetween gopher and the web, striving to address (perceived) limitations of one while avoiding the (undeniable) pitfalls of the other.

To put it into my own words, Gemini is a text-only web protocol built as a reaction against the modern web. But what is wrong with the modern web? Let me answer that with a few of Drew DeVault's blog posts:

Okay, so you have some context. What now? Since Gemini is a separate protocol from www (the "web"), you need to access it in a different way. There are two main ways I do this right now: Since you're viewing this in a web browser, an HTTP proxy might be easier for you to start. In that case, I am aware of two proxies. Vulpes looks good, but it doesn't render verbatim text if it appears as a header, so you'll miss out on some content. I do like the theme a lot, however. Mozz doesn't look as nice, and includes request metadata in the output; but is functionally complete as far as I can tell.

If you're ready for direct gemini interactions, then I can say I've enjoyed using AV-98.
