It's the simplest planner available. Users type plain-language commands into Coolendar—no need for precise syntax—hashtagging keywords to organize similar tasks. For example, "Monday, 5 p.m., don't forget to pick up the #dry-cleaning." Coolendar automatically slots these into a to-do list and will send Gmail and Google Talk reminders. The free site syncs with other calendars and has an app for smartphones.
Microryza.com connects scientists with donors who can potentially fund their research. The Seattle-based staff screens proposed projects for feasibility and novelty and runs checks on applicants to prevent fraud. Once approved, researchers post videos and a Q&A about their projects on the site. As with Kickstarter, visitors can back the project of their choice.
Even do-it-yourself work often requires the resources of more than one person. CollabFinder.com connects DIYers with developers, designers and other creative types who have complementary skills needed to handle complex tasks and finish projects. Users can register for free on Facebook and search for a potential collaborator by skill, location or interest—for example, a documentary editor in Cleveland focused on environmental issues—or even assemble a team.
