To attract more members, maybe we should open more threads on topics other than political debate and political news, because in the end it tends to be repetitive at times.
For instance, there were several threads on scientific topics in the past that brought up very interesting discussions.
Why not talk about art and literature too from time to time ? Why not share personal stories and experiences ? Why not share financial or professional tips ? To a reasonable extent, of course, without overshadowing the primary purpose.
Also, I think it would help if we could allow for a little more diversity of opinions on economic and social issues. For instance, I am nowhere near a socialist, but I do not view taxes necessarily as a robbery, nor am I opposed to all forms of redistribution of wealth. I can't begin to discuss these issues at length now, but wouldn't it be interesting to have a debate over this at some point ?
