I'm a Dutch Rubyist residing in Norway.
Want to leave a comment on my photographs?
Please don't write something like "please have a look at my pictures" because it makes your comment look insincere.
It makes you look like someone who only is looking for comments on his own work, rather than someone who genuinely likes a photograph. I'm more inclined to look at the gallery of someone who leaves a detailed critique, than someone who basically begs for comments.
I would rather get a long comment describing how I could improve my photograph, than just a one-liner saying you 'liked' it, or Faved and Voted it.
