The people who used to keep Rotonews up and
running are now doing the same work for a site called
Rotowire. Strangely, Rotonews seems to have been
resurrected, I'm not sure by whom. My intuition is that
Rotowire is probably more useful at this point.
If
you're interest is specific to fantasy baseball then you
can get some decent info at BaseballHQ.com, which has
both news and analysis in both its free and its
subscription-based sections. (Full disclosure: I do a modest amount
of work for BaseballHQ.)
Yahoo!, ESPN, and
CNNSI all have good on-line fantasy sections. James
Quintong of TRASH could probably tell you more about the
latter. :-)
