My two cents worth...
arabiadotcom was what arabia.com was called and may cause confusion especially since the site was popular but now leads to a marriage service.
Digital and tech arabia are all taken I think and should be researched before going into that.
how does arabwebscape sound? arabdigitalscape? arabkeyboard arabiankeyboard, arabiakeys (see the theme?)
arabiawired? wirarabia?
Arab crunch sounds like a cereal to me. adding 2.0 means you are dated when the next big thing comes around.
And I agree with ghassan on both the unique name and wordpress being a great place to blog.
