jaxtr (yep, the first character is supposed to be lower case) is another one of those web services that sort-of-kind-of makes sense for a moment and then makes me scratch my head. jaxtr lets you place a special link on your web page. People can click on this link and a call is routed to your phone (mobile or wired). According to jaxtr one of the advantages is it allows easy and cheap international calling. There must be something to this because both Mashable and TechCrunch noted that jaxtr has grown from 500,000 users to 5 million users in just 5 months. Me? I don't like talking on the phone much anyway. So, I'll pass on this one.
