There's a URL http://arxiv.org/tb/recent that shows all recent trackbacks. It's amusing that MO dominates this list!

]]>@Mariano: you mean the link labelled "link" on the mathscinet reviews? I always right click that to copy the link location when I have to send e-mails or post here.
]]>(1) is a bit interesting. I have some reservations about what you mean by a "recommendation service". Many of us already have a backlog of "papers that one ought to read" that is more than "papers that one can physically read in a lifetime"... :p Any further unsolicited recommendations are likely to be ignored. An integration with MREF will presumably save, on average, a few seconds of my time each day.
(Of course, considering how we have no access to the source of MO, the standard "this discussion will be purely academic and possibly not implementable" disclaimer applies.)
