LOCKHART STEELE — With due respect to Nicholas Butterworth, the New York internet comeback of 2006 has to go to Jeffrey Dachis. Dachis, you may recall (if your brain hasn't permanently suppressed the memories from that weekend in Vegas), started the web design firm Razorfish in the mid-1990s, took it public, rocketed to glory, then watched the firm crash, burn, and then, after his departure, rise from the ashes as Avenue A Razorfish and become profitable again. Which is why it made a delicious kind of sense that this year, Dachis would also want back in.
