There were tons of articles about Wordpress Plugins, Wordpress Most Useful Plugins, Wordpress Essential Plugins etc. Everyone is trying to create their own list and so do we 
But our list is different, we tried to list only plugins you can use when building a typical business website, where blog is just a part of the website, and not a main feature.
We’re using these plugins on a daily basis, some of them are simply essential for every website (All In One SEO Pack, Google XML Sitemaps, cformsII, Insights, Search Everything), some of them we’re using in particular cases (WP-PageNavi, NextGen Gallery, Flash Video Player) and some we used only once so far (WP AutoSuggest, WP-Syntax, WP-Polls, Twitter Tools).
