Yes, there should be a like button. Heres what you should do:
Make the '+2' and '+7' etc. appear very discretely in the top corner of the post box. I don't want to have a giant +128 beside all of my posts, as it would distract people from the interesting and informative contents of said posts.
DO NOT make the posts in the thread go in order of the number of likes they have received.








My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
