HowToConvert.org offers over a two dozen digital format conversion articles with simple step by step instructions. Its design is quite pleasing on the eye, but has some room for improvement, especially with regards to the way ads are displayed on article pages.
A pretty good looking database of nearly 250 short biographies.
Interesting and potentially quite useful resource providing info on what do certain acronyms, words or terms stand for as well as more about what they represent. However it does require some fixes in terms of design, most importantly fixing the missing images.
First impressions of WhatCauses.net are somewhat ruined by the missing/broken teaser images on the homepage making it seem unprofessional or incomplete, but other than that it's a pretty decent resource of causes primarily of various health related conditions.
A decent disease symptoms database covering over 50 diseases along with causes and treatment information. Some further design polish couldn't hurt it.
Great, elegant looking resource about discoveries answering not only the question of who discovered "it", but also providing further information about what was discovered.
WhoInventedIt.com is a journey of inventions, a cool looking site with over two hundred articles about inventions, who made them, how they came about and more. Needs a search box to search through them though! Aside from that, its other imperfections are minor.
WhereDoes.org provides information about where do certain well known people live and more about them, their properties, career, activities and so on, good for everyone curious to find out more about a famous (or even not so famous) person they might admire and having some casual entertainment value. In terms of design, however, the site is quite decent with a few non-critical issues, but could be more unique.
A great cookie recipes site with easy to follow recipes presented in quite a pleasant design, albeit somewhat detracted from by unfortunate ad positioning.
RecipeIdeas.org is quite a pleasant looking site, but its design is a little detracted from by some issues on article pages which require some polish. However it's purpose and focus is clear and its content is a winner.
