I wouldn't say that's a manip. Blurring layers and changing the blend mode, with some stamping thrown in does not make an image a photomanipulation.
Texturing is exactly what it sounds like - you take a texture (go on http://sxc.hu and search for textures, or go to http://imageafter.com), place it on the image, and adjust the blend mode so that it doesn't overbear the image but still lends texture (and sometimes color) to it.
This is a photomanip 😛
And yeah that's one of mine 😛
