Twook4it allows you to find people that have put out requests to find something else. Meaning they are searching for help, an item, a job, an employee. Whatever. This site brings the two of you together.
To simplify..they watch for tweets where someone asks for something. You go in to their site and put in some keyword. it then tells who who is looking for that keyword. Sounds simple but reading the past searches page was actually funny. Not sure of who would be looking for a heart attack.
