Blame it on Clinton, Gore and Celine Dion, who were causing the intrepid Internet World partiers travails in their travels. Exactis.com was hosting a small soiree at the 21 Club, for clients like TheStreet.com and forbes.com. I met Warren Greenbergand Peter Cannizzo of MCIWorldcom, who were sampling the salmon and hinting at another merger with the next major telco company. Will it happen? Find out next week! Mitchell Cohen and Michael Rosol of Exactis were entertaining their guests and as we chatted about their services, I enjoyed a classic "21" Burger hors d'oeuvre. Seth Price was enjoying some time at a separate table with Karin Nevils, an Intranet developer at Doubleclick.
