More playing with forms in feeds... :-)
If you've got a Yahoo! ID you can fill out the form below and send off a free SMS to anyone in the U.S. (If you're not logged into Y!, it'll prompt you for your user ID and password before it sends):
The neat thing is that because the form uses GET, you can actually create a link on your page that uses the same tech: Send "This is a test" to 415-555-1234. [Update: Tim Bray says: "Don't do this, you moron!" Doh! Duly noted.]
Yeah, you can pretty much do the same with a teleflip.com email, but this will have a "from" of your Yahoo Mail, which is actually quite useful, as the recipient can respond instantly with an MMS message. If you have filters set up on your Y! Mail, you can then get notified as well... You can also pop your phone number in the form by default and put this in the side of your blog, for example, and have people contact you where ever you are (as long as they have a Y! ID) - that's pretty cool if you think about it.
I was going to put my phone number in the above forms, but I was thinking about how not fun it would be to have my phone beep for the next several days as people played with it, and for random phone calls from strangers asking me technical support questions (it happens all the time). What would be really cool is an anonymizing text messaging service no? Sign up and get a number that anyone can use on their phones to send text messages to, but doesn't actually correspond with their phone number. Other times people find my mobile number and send me random text messages, but then don't sign the message with their name... at least with email you can guess their name sometimes, with SMS it's a complete mystery.
Hmm. I guess that's called "Push Email" isn't it? Heheh.
