Critics of the Turkish Government have been turning increasingly to social media to voice their opposition.
Now one site - Twitter - has been blocked, after accusations of corruption concerning the Turkish Prime Minister Recep Tayyip Erdogan and his inner circle.
Allegations that have been denied.
There have been threats also to ban Facebook and YouTube.
And the government also recently tightened control of the internet - nearly 8,000 websites are jammed.
But Turkish users of Twitter have already found ways around the the ban including the President Abdullah Gul, who tweeted - 'A complete ban of social media platforms cannot be approved.'
So, what does this mean for freedom of expression in Turkey?
