Let me mention about "Snap" - the company which has amazed me since last year with its totally innovative ideas & product offerings - all aimed at making end user experience more rich & hassle free. Snap Shot, Snap Search, Snap Preview - all of 'em basically are awesome products since they let an end user know about a page's content, look & feel even before clicking on its HyperLink. Their latest blog post shows that they are even planning to make an entry in Web Adv Space with "Snap Shares" - It would basically render the Real time Contextual Ads as user navigates across a Web Page. On face of it, the idea appears impressive since it would be like Dynamic Google Ads which are displayed at relevant places only. (No more Leaderboard/Square/Vertical Banner Selection hassles :)). God knows how they'll do this seemingly challenging enhancement.
CO2 Saver - this tool is a light-weight program which runs on Desktop & tweaks user's Power Mgmt settings to reduce the energy use when the PC is idle. And yes, as a user you are empowered to change the Power Settings anytime of course.
I simply fell in love with this tool - just add up the CO2 you are saving per day (Tool shows you the metrics as well) and multiply it my 365 and you'll realize why am I so excited about it. So, lets go & make a difference....!
