Google has just released Page Speed Online. Page Speed Online is a simple tool that tells you how fast a web page loads in a desktop browser or mobile device.

Tinychat is a new application that lets you host group video chat rooms on your website without installing any software. Like Wibiya (see the Wibiya toolbar at the bottom of the Kikabink News website), Tinychat is a toolbar you can integrate into your web pages.

Once up and running, you can use your web camera and microphone to host video chat sessions with visitors to your site. You can even share up to 12 simultaneous broadcasts. Tinychat isn’t limited to video either – you can also use it for text and audio chat.

The easier it is for visitors to read your website content, the more likely they WILL read your content, click on your ads, subscribe to your newsletters, buy your products or take other actions you want them to take.

Which begs the question? How readable is your website? Juicy Studio offers a free readability test to let you check this.
