Apparently, idea organizers are either easy to build software os a standard app is available - wridea is one in many. As Zoho offers the zohoplanner(review), wridea does almost the same thing. Key difference ? The gui of the site. Wridea looks very high-tech and futuristic, where zohoplanner looks clean and simple. I wonder if there is a future for ida organizers - there are so many out there already. If you want to discover more webbased software like this, have a look at Sacred Cow Dung's list.
