cplittleton: I just voted my way through the challenge ... my overall reaction to the entries is that 'solitude' is not always 'loneliness'. A quick look at both loneliness and solitude in the dictionary emphasized this point. The entries are split between the two; I voted according to my interpretation.
Before those that submitted 'loneliness' pix complain, the challenge host hinted at the difference in his introduction saying "Where the loneliness ...", asking more for a place and less for a mood.
In a way I agree with you and that was one of my doubts when I was picking a photo for entry. But at the same time, I guess that introduction can be open for interpretation and since the picture seemed to blur both definitions in my eyes I opted for that one and my votes reflect that also.
In the end it was a lot of fun and this challenge and comment it's my way to say hello to all of you after lurking a little on the foruns. :)
