With the number of great SharePoint resources out there, it is sometimes difficult to find the specific resource or content that you need. Michal Gideoni and a partner released a great tool that's built on SharePoint for SharePoint.
The concept is very simple. The resource metadata (title, description, location, et cetera) in a SharePoint list and can be pivoted based on audience, level and other metadata. If you have feedback or suggestions on what else should be included, please be sure to submit it from the site. Here's the tool - check it out: http://sharepoint.microsoft.com/readiness.
This is useful when you're looking for a specific type of content. Otherwise, I continue recommend these five great places (besides the SharePoint sections of MSDN, Microsoft.com & TechNet) to bookmark for frequent updates.
