When you add GrandCentral’s WebCall button to your blog, your readers can easily call your phone or leave voicemails without ever seeing your telephone number. [...]
Your voicemail is all kept in a visual online inbox that is easy to manage. Store as many as you like for as long as you like, or post them to your blog so anyone can hear them.
For the unfamiliar, GrandCentral is like a voicemail box “email style,” that allows users to call friends, forward incoming calls to multiple numbers and mark annoying calls as spam (which humorously tells telemarketers that “this number has been disconnected”).
Despite the fact that its still in an “invite only” beta, Google is opening up this feature towards blogger users, although WordPress (as well as Six Apart) fans should be able to join in the fun by clicking here.
In the future hopefully Google will consider allowing users to post their thoughts via a phone call (like they use to with Audio Blogger before the site went kaputt), although giving readers another way to contact their blog authors anonymously is a great way to help bloggers build upon their current audience.
