Use real Markdown parsing
Some people might be confused by the markdown syntax and later realized that it's not parsed that way.
Wouldn't yaml be more appropriate? You get automatic parsing for free, it's a quite readable syntax and, because it's a hierarchical structure, you can later on add more metadata easily.
I just feel more comfortable writing in Markdown :) Currently, my plan is to add a simple way of linkifying text so that people can just type:
04/09/1998 - [Google is founded](http://google.com/)
I admit that Markdown is far more readable but then again, you couldn't add more data (i.e. descriptions) to items.
Adding more (meta)data is tempting but making is super simple is my priority for now.
Adding description could be something like this:
- 04/09/1998 - [Google is founded](http://google.com/)
> Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University.
Hm, could be! Neat project btw, it certainly comes handy.
