Well first I go by author, then titles.
I don't spend as much time as I used to here, so these days I am more selective in my reading, if they are poet I am not familar with I go by title and also the no. of replies. If they have a low no. of replies (i hate seeing poems ignored in the rush of forum traffic) I will read and reply if I like the poem.
Too early for the rainbow, too early for the dove These are the final days, this is the darkness, this is the flood
