Although I’ve been a heavy Skype user for over two years, I still keep an eye on Gizmo. Apparently, so does Om Malik because he’s reporting that Gizmo just went sans client. Once the service launches, you’ll be able to get a small browser plug-in from Gizmocall.com so you too can be VoIP’ing right through your web browser via Flash support. Moving away from an installed client application definitely opens up the door to more potential adoption of the service; something I think Skype might want to consider.
I’m sure we’ve got both Skyper’s and Gizmo gabbers out there: is a web-based VoIP app appealing to your gift of gab? I’ve stuck with Skype mainly due to the mobile client; since some mobile browsers don’t support Flash, I think I’ll keep my VoIP needs with Skype…for now.
