Ugandans angered by new tax for using social media

About 17 million of Uganda's 41 million people are active internet users.

A new tax on social media has taken effect in Uganda, angering many who see the revenue measure as an attack on free speech.

The tax on users of sites such as Facebook was first proposed by long-time leader Yoweri Museveni, who complained of online gossip in a March letter that urged the finance minister to raise money "to cope with the consequences."
