Re: 1 & 2 Colors, accessibility & navigation
I am an artist, a blogger, a small business person and I’m visually impaired, so when it comes to colors I do have information to share. If you visit my blog you will find a great deal of information on this topic.

The colors you choose will have a direct effect on how the public perceives your company or product. Colors evoke emotions and as we wish our visitors to stay and read, it makes good sense to choose restful colors that showcase products without causing distraction. It’s also important to note that your color choices can present challenges to the visually impaired. Aside from making your site accessible to visually challenged readers, including those who are colorblind, did you know that:
a. An accessible website is more likely to be ranked well with the search engines than an inaccessible website;
b. By designing a colorblind accessible website, you are also targeting PDAs, 3G phones, and similar technological devices that are used for web access. This link is a useful one http://www.allwebdesignresources.com/webdesignblogs/graphics/how-to-design-web-accessible-pages-for-the-colorblind/

6. JavaScript
I agree with the gist of your point which suggests reducing the the amount of javascript running on your site. Your site’s load time will increase in accord with the number of JavaScripts you have running.

JavaScript files load differently than other HTML elements. While HTML is loading, the rest of the page continues to download. But in the case of JavaScript the element must completely load before the rest of the page can continue. To counter this problem, place all JavaScript files at the end of a document; and, if you have third party javascript and links in your sidebar, then put them in at the bottom of the sidebar. BTW there’s a WP plugin called “JavaScript To Footer” that can do this.

Best wishes for effective networking.

I think one of the things that makes a good business website is simplicity of layout. Most businesses will benefit from a clean, white-space-driven business website that’s easy to navigate.

Sometimes less is more, and I think that’s the case on most business websites.

Websites are the most preferred way for promoting a business online. For that reason, you must focus on blunders that are responsible to hurt the website performance….
