Here is how to search the Egyptian Blogosphere. I guess this would be very useful.

Go to feedster advanced search, type your keyword and then add this OPML file in the space titled "Limit to feeds in this OPML URL".

UPDATE: the above photos is a bit old please use this url http://www.manalaa.net/aggregator2/opml

One more thing, feedster is a little bit strange. You will have to search every time from the Advanced search page.

Here are several examples: * khan pope * schiavo hariri * tsunami جاهين

Note that you may get a Bad Database Request error. This is a bug in Feedster you can try again or change the keyword.
