No, not really.
What people want Tor to be is an Internet that is free and secure and provides information for people with infringed freedoms. However, that's actually not much information in total, and Tor has ended up being a repository for very illegal things, not things that are just illegal in Iran, but things that are very illegal in the US.
I completely understand that if a huge number of 'normal' people ran nodes it would make it more secure and less suspect... but, in the process of that you are helping the illegal activities become more secure, less suspect and safe. And with cops confiscating exit node computers and possibly making their life uncomfortable, and with recent takedowns of pedofiles and drug dealers, the Tor system doesn't seem all that secure. The illusion of security is worse than no security.
