Last night we went to another Dallas Museum of Art Late Night event and got to see the new Societe Anonyme exhibit. There was a quote by Francis Picabia in the description of one of the paintings: He said "Art is useless, and impossible to justify", and went right on doing it.
Christian pointed out that the sentence also makes sense as:
"Web development is useless, and impossible to justify"
or, in my case,
"Email marketing is useless, and impossible to justify"
I think mine makes the most sense :-)
