Yup the link shorteners often help in disguising the source and even annoymysers helps too... I guess thats the option available for the TPB guys to implement it without being blocked by FB guys

i would agree to nweaver's argument.. moreover feasibility of the encyclopedia is also to be considered..
a guy in africa with would have a better access to a wikipedia rather than the britannica encyclopedia...

wikipedia could be used to do collect information about the old topics.. but for the recent topics [dynamic topics ] it could be used only for the background information
