The Blog Herald counts over 60 million blogs worldwide for May.
The Blog Herald hazards a guess there are approx 100,000 blogs in the mid east. They even quoted Iraq Blog Count numbers, almost (thankyou note to Blog Herald - if you are reading, 132 blogs have been counted here. Not to say it won't reach 151 one day. To be less tactful. Not 151 yet. Being as interested in accuracy as most other bloggers are. That still sounds a bit nebulous doesn't it, oh well).
Arabblogcount has linked 200.
The wiki estimates there are 65,000 active Iranian weblogs in persian (out of 2,000,000) although their source link, blogcensus, was busted when I tried visiting it.
And Blogcount.com suggests measuring overlap.
"nuff counting now, see you later when have (another) moment to drop by.
