After the long and embarrassing Skype global outage in August, you would think Skype would want to avoid further PR disasters. But now we find out that Skype patches high-risk flaw but didn't warn the public for a month. Skype is a killer-app that is here to stay in the home and even business world and it is still the best-of-breed VoIP and video conferencing applications on the planet, but the public wants full transparency on these incidents. Covering up these things just turn a minor disaster it to a big one and it's going to hurt Skype in the long run.
On the bright side, I've updated my version of Skype to 18.104.22.168 and I was pleasantly surprised by improved video conferencing quality in the update. To get improved video quality, you must have a dual-core processor, minimum 384 kbps upstream/downstream Internet, and a premium Logitech camera like the QuickCam Pro 9000 (I am an impressed owner).
Update 12/13/2007 - Skype updated to version 22.214.171.124 yesterday. It's getting hard to keep track of these updates one after another.
