TxtDrop is a new web-to-sms widget. A small html form you can add to your site, your myspace profile, your OiH directory listing or whatever. The form allows a visitor to send you an SMS message (SMS = texting) for faster response. Not the be-all, but another method of serving the visitor on their terms.
I first heard about txtDrop by seeing this post on TechCrunch. But I could not recommend it to anyone until I figured out the privacy and security concerns. The same reason I still won’t use Riya. We don’t want everyone sending us spam txt in the middle of a movie. Or selling it to someone offering great rates on mortgages.
