Quoting Lady Bracknell is becoming tedious, but for two leading local area networking companies to lose their top officer, and one of them to lose two does seem a bit careless: 3Com Corp’s president William Carricco and the general manager of its Bridge Communications division, Judith Estrin, have both resigned, while Novell Inc has lost Louis Cole, its executive vice president responsible for software products – and Alex Brown analyst Douglas Whitman is emphatic that the news is bad, particularly in the case of 3Com; I think its very serious, he told Dow Jones, they’ve lost two of the best people in the LAN industry; he was less concerned about the loss suffered by Novell, which is due to announce the ability to support Apple Macintoshes in Novell nets on Tuesday next week.
