Kasabi has just moved into public beta. The private beta is over, and Kasabi is openly ready and willing to become your data marketplace. This is similar to what the primates over at InfoChimps are doing: building a community around data sets and APIs.

OfficeRecovery is a one-stop-shop for a wide range of data recovery issues. The website provides software tools that facilitate the restoration of lost emails and mailboxes, repair corrupted databases and damaged documents, and retrieve files from damaged external storage devices. The OfficeRecovery Web API allows developers to embed this service into their own sites and to use the resources for remote recovery of corrupted data.
