I met lots ‘n lots of people today, starting at 7:30 a.m. at Thomas Edison State College for the Trenton Small Business Week, which continues Thursday. Jane Gore of Amboy Bank and I got lost together in the State House parking lot but arrived at Thomas Edison State College in time to hear Doug Dixon of Manifest-Tech wow the Princeton Chamber breakfast audience with a tour-de-force demo of gadgets that are potentially useful for business, including an Android app that provides voice translations. Speak into it and click to hear it in French. Plus an app so you can program your DVD remotely.

Then Glenn Gabe of G-Square Interactive dashed cold water in the face of anyone who thought getting an ROI for social media was easy. To be successful, you need to allocate 10 to 20 hours a week to it — and that’s when you know what you’re doing.

After a stint of Bible study at my church (did you know that Adam and Eve had a 3rd son named Seth?), and a failed interview (my source couldn’t take my scheduled call), I went to Charlie Brown’s for the Einstein’s Alley Entrepreneurs Collective, a group of techie entrepreneurs. Eric Kutner had enlisted a most intriguing panel of sports entrepreneurs (top, from left, Tony Caruso, (sports & entertainment attorney), Howard Moses (Blue Star Jets), John Romanowich (SightLogix), and Sam McCleery (formerly with Prince and now Princeton Video Image.) Second photo is Mark Silverman, ex of Ernst & Young, and Romanowich. For more photos (Moses, Kutner, and McCleery and the EA organizers, Steven Georges and Marion Reinson of To the Point Communication try this link.

New to me though not to Princeton was Mark Hall, president and CEO of EGOEAST, a public relations, marketing, and branding firm with the toniest business card I have ever seen. It was illegible to me — one shade of beige, with raised letters. I had to rub it with a pencil, like a stone carving, to read it. The website is similarly styled.

Curious, I turned back to the cards collected this morning and smiled to discover how evocative they were of the entrepreneurs and their businesses. Edgy but dignified for architect Marina Rubina, straitlaced-corporate for Melinda Skarupsky who represents a security service that I won’t mention so as not to get her in trouble, colorful in both Spanish and English for Hilda Lopez of Mercer Business & Technical School, minimal for project management consultant Steven Rabbe, and quietly strong for Joan Brame’s Empower Fitness.

There on the top is my new business card from Document Depot, complete with Twitter handle. I’ve had the same logo — an abstract dancer because I used to be a dance critic — for too long to count. The new ones have my Twitter handle but tonight, from David Gange at the EA meeting, I found to my horror that the Tweets show up on everybody’s LinkedIn pages. I apologize to that network; I didn’t mean for the Tweets to go to you. If Dixon or Gabe can tell me how to turn them off, that would complete the circle of the day’s learning.
