Wordmark Logo Examples

I think this example is very effective.  I like the font choice and the fact that only a slight change in the P was enough to evoke the idea of a pin or thumbtack.

I don't know what this product or company is but I like the displaced Q.  The progressive size of the letters adds to the feeling of a tight space. 

I like the simplicity of this logo.  The upside down As don't seem to make the word any more difficult to read, which I wouldn't have expected.
