An interesting discussion is definitely worth comment.
I do believe that you ought to write more about this subject matter,
it might not be a taboo matter but usually folks don't discuss these issues. To the next! Cheers!!

I know this if off topic but I'm looking into starting my own blog and was wondering what all is required to get set up? I'm assuming
having a blog like yours would cost a pretty penny?
I'm not very internet smart so I'm not 100% positive.
Any tips or advice would be greatly appreciated.
Thanks
