In your business, Angela & Stephen Hardiman / HouseTie.com , probably any place where there are REALTORS is a good place to be.  The big events may give you the most exposure, but the smaller events may offer a better opportunity to connect one-on-one with agents.  

RealtorQuest.  Largest show and easily accessible.  Most years it has some good presentations.

WRA and KW

Generally dont attend any, but attend a few woodland owner conventions every few years.

I attend our State convention, and sometimes the NAR convention.    There have been a couple tech trade shows I enjoyed too.   Like to know what new gadgets and tools could be useful.

None. Don't need more people trying to sell me products and services that i don't need.

i do enjoy trade shows of many varieties. the ideas and the fuel to do better after are worth it

I do not attend.  Am I missing something?

Our local association has one, I attend the one at NAR.

We go to NAR convention--always great to network

The National Association of Home Builders annual shows are outstanding and you have the opportunity to network with builders and developers.

None.
