I don't use many of the other gadgets/toys. Well, Weather Underground, Woot watcher, Google Finance are useful, but I could live without them.
Are there alternative sites that provide a similar function?

"Level 3 accuses Comcast of unfairly using its clout as the dominant U.S. cable provider"
By Cecilia Kang
"An online networking company that carries video feeds for Netflix has accused cable giant Comcast of demanding unfair fees to provide that video to home subscribers, raising questions about Comcast’s power to control consumers’ access to the Internet.
Level 3, a Colorado-based Internet company whose main client is the video giant Netflix, on Monday said Comcast’s action amounts to setting up a “toll booth” on the Internet.
The issue arises as federal regulators consider Comcast’s proposed purchase of a controlling interest in NBC-Universal, which rivals have said will give the cable company too much power over both programming and the means to distribute it.
This action by Comcast threatens the open Internet and is a clear abuse of the dominant control that Comcast exerts in broadband access markets as the nation’s largest cable provider,” Level 3’s chief legal officer, Thomas Stortz, said in a news release.
Comcast disputed Level 3’s claims, saying its demand for fees is unrelated to the content that Level 3 wants delivered to consumers.
“Comcast offered Level 3 the same terms it offers to Level 3’s content delivery network competitors for the same traffic,” Joe Waz, Comcast’s senior vice president for external affairs, said in a statement. “But Level 3 is trying to undercut its . . . competitors by claiming it’s entitled to be treated differently and trying to force Comcast to give Level 3 unlimited and highly imbalanced traffic and shift all the cost onto Comcast and its customers.”"

Then, ask the students to think of one thing they want to talk about. Let them bring the items into the classroom with lab time to take them apart, guided by the instructor, and other students. They can choose junk in their basement or garage, or buy something cheap from a second-hand store. Or even from the local recycling center. Need basic tools, multimeters (inexpensive from Harbor Freight -- good enough for this class), etc Provide some basic instructions on safety and tool usage.
They might even figure out how to fix something.
Then, for the rest of the couse, each student does their presentation. (They also "accidentally" learn some presentation skills.)
The best way to learn is to teach!
Years ago, I participated in a "How Things Work" seminar at MIT just like this. Great stuff!
This fall, San Francisco will test 6,000 of its 24,000 metered parking spaces in the nation's most ambitious trial of a wireless sensor network that will announce which of the spaces are free at any moment. Drivers will be alerted to empty parking places either by displays on street signs, or by looking at maps on screens of their smartphones. They may even be able to pay for parking by cellphone, and add to the parking meter from their phones without returning to the car.
Any guesses on the when this will be hacked?
Like, "reserving" an empty spot by convincing a sensor that a car is actually parked there. Of course, in San Francisco, this will be for naught, since spaces don't stay empty for any longer.
Or, perhaps using the wireless mesh network for some other purpose?"
