If the likes of Information Week and Scoble were bound to such trademark restrictions (and they exist for other companies, not just Linden Lab) then we'd have examples galore of how this applied, but they simply don't abide by these rules. The mainstream press, the professional writers, are not bound by conditions such as this and this is where the whole process has been made extremely messy.

This is intended to stop people infringing on Linden Lab's trademarks in relation to business, it's to stop other virtual worlds using Second Life, it's to stop business pretending to be Linden Lab and trading off their name. If you're selling products inworld or outside of it via websites that offer such services then you should be following these trademark guidelines to the letter.

However if you're simply writing about your adventures inworld, questioning policy, praising policy, then you shouldn't have this big stick hanging over you.
