With the right tool, one can do just about anything.
With a long enough lever, and a stationary fulcrum, one could move the Earth.
With the right software application, one could uncover just about any of the
hidden nuggets on the Internet.
None of the sites or products is providing any payback to me. It's just a
list to give you some ideas about the kinds of things you might like doing on
the Net. Good hunting.
