I suspect that the owners of Num Sum and iRows, which are online spreadsheet services, are desperately trying to find someone at Google to speak with. If not, they should be! With Google's acquisition of Writely, adding something like iRows or Num Sum would be the perfect complement. And we can only assume that Google will add an online spreadsheet service to its products, so when they do, Num Sum and iRows doesn't stand a chance of competing. Better to sell out than die out!
