i dont share the same feeling. i've been here for quite a long time now..and ppl i know or network with have lived here for decades, and i have never found anyone trying to show off..if anything from my expericene they have always given me a +ve feedback, suggestion, advice, with i whole heartedly appreciate. and ya convention is a good networking event,,if anything it is a networking event, so you know other ppl from diff aspect of life , so i think its perfectly fine to pass out your business card, if you're a contributor..then it doenst matter if their profession has anything to do withyou,,may be down the road you might come across someone who might need their service...and if you wanted you could pass their business card to them...ofcourse if you wanted to. same with donald trump...depends on how you see it, he is a an excellent mekerter..definetely a capitalistic...we all could use or atleast listen to what he has to say...he's an icon...whats wrong in talking about what he has doen and try to learn from it... dunno now may be you might call me a showoff too..well be my guest.
