I was at TiECon East last week and there was obviously business card exchange going on. Now, there are few things I’ve learned about what to do at networking events, and what not to do.
What to do? Remember who you emailed post-conference, and who emailed you back.
What not to do? Email a cut/copy/paste of your services to someone, and then re-email it two days later, after they responded kindly to the first one.
