Content To Be Shared

we have content at http://www.mathsfix.co.uk/blog/

content is being added daily

would like this content to be shared via facebook, twitter and google +

we only have a twitter account

we are not looking for likes or followers

but for others to perhaps like this and post it oh their accounts

i.e. generally looking for the content to be shared and for that to act as links back to the site

hope it makes sense

thanks
