I've found some interesting sites, and I want to share them with you. So let's start with the first.

Compare fonts for screen
This one is to select some fonts that are commonly used but you can select fonts from your system too. For what? To compare different fonts in a lorem-ipsum paragraph to see which is the [best]. (I wrote this in brackets because is not the absolutely best but the one which fit in your website if you have a good eye to see design patterns and evaluate which is good and readable and which one not.)

Colour Contrast Check
I don't remember where I found this site, but this is cool to see if the text with a variable color is readable with a background color (you choose both, text color and background). Simple and useful.

Review my web!
This tool is really amazing, you can compare your site with others in the web. It's about Search Engine Optimization and Traffic, and some other qualities you could choose. The bad point? you have to send your email and we don't know if they will use it for spam chains ... anyway, useful for great sites.

Smush It!
There is the one I like the most. This tool isn't just an image uploading system but also an image optimization system. You can select more than one image at a time, and there is a plugin available for Firefox! EXCITING--

As you can see I've changed my WP Theme... I think this one is better and simple for me, my TODO list is so large... Soon I'll post about WordPress tools, but I'm busy right now to make a larger post ... I have to finish some work and to start some other. Currently I'm with a Flash application and I'll be working on Justicia y Dignidad (Justice & Dignity), a new politic party... I think this is one of the best projects I've received so I'll try to do a web standards compliant site, with fresh design.
