| One common problem is that while being static your website still needs a contact form. | |
| Here's a solution for this problem using Newman API (http://www.newmanapi.com). --> | |

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

| # We first start by creating a way of escaping the characters that have special | |
| # meaning for html, while making sure we don't end up double-escaping at any | |
| # point. The easiest way to do this is to create an S3 class that allows us to | |
| # distinguish between regular text (that needs escaping) and html (that | |
| # doesn't). | |
| # | |
| # We then write an escape method that leaves html unchanged and escapes the | |
| # special characters (&, <, >) in ordinary text. We also add a method for lists | |
| # for convenience |
