well there goes plaxo down the crapper.. of late they have realy been improving their service mostly becuause of the fact they actualy bothered to listen to user feedback and suggestions which is something totaly against the nature of comcast.
I use Plaxo myself to help manage synching of address books and calender between multiple apps and sites like google as well. It also serves as an online backup as well. There are no alternatives out there to right now. So I'm not sure what many others like myself will do if Comcast buys up Plaxo.
reply to crucialcolin Plaxo has a deal with Comcast (in terms of plug-ins for the e-mail side of their HSI service) that mirrors a similar deal with AOL. However, with AOL shedding customers, Plaxo needs more income, so a Comcast deal makes sense (since it's unlikely that TWQ is interested).
