I planned to do this for a while. Today, I finally got it done. On the top left side of this page, you find now two search boxes. One search box offers a search for this site only. You might remember that you saw something here that you want to read again. Enter your query and Google delivers.
The second search box extends the search to external photo related blogs, which I am currently subscribed to. Currently, 28 blogs are included, but this number will grow soon to give you the best possible resource on photo related queries.
If you have any suggestions for sites to be included, put them in as a comment.
