I think a lot of times, people are here just to have a conversation. I wouldn't go so far as to say someone who is pontificating and could have done a web search to verify their thoughts and opinions is being lazy.

This might be a case of just different standards for communication here. One person might want the absolute facts and assumes everyone posting should do their due diligence to verify everything they say, but others are okay with just shooting the shit (to varying degrees).
