Comment Sounds plenty educational to me (Score 1) 190

Figuring out how to make all of those connections, swap SD cards, etc -- that all sounds very educational to me. Not every computing device has to be as simple to use as an iPad.

In some places access to these sites is blocked. Some people have taken up the cause and have started posting their Tor bridge links. Using these bridges people can bypass firewalls and access proxies. I have posted my bridge link on my blog and on my Twitter page. I have no way of measuring if this is helping in anyway but maybe it's worth a shot to help."
