Here is the site Addict-o-matic.com where you can just enter a few key words for the current hot topics that you are interested in and then you will get all the returned results from various automatic searches on feeds (Web 2.0) and news on the web (Web 1.0).
For example, if you want to know about the latest news and updates on the Pentax K-7, just key in "Pentax K-7" in their front page and it will be directed to:-
http://addictomatic.com/topic/Pentax+K-7
Then, you will get all the up-to-the-minute results as returned in the above link, which is also bookmarkable. (Well, many returns will directly or indirectly point to my Blog, though! :-))
I highly recommend this website and engine, which is highly modern, and probably is the best web-tool for any people who are suffered from any serious LBA (Lens Buying Addiction), CBA (Camera Buying Addiction) or even WBA (Web Browsing Addiction)! Good luck!
Well, the website is called "Addict-o-matic", that simply means Automatic Robot for your Addiction! Isn't it? Really nice! (My Thumb Up)
