After writing the post immediately below it occurred to me that although there is much talk about the discovery of electronically stored evidence (ESI), the admissibility of ESI is addressed far less often. In fact, in the two day conference I linked to in that post, the topic is not even mentioned.
For the interested, there are two important starting places for this topic. The first is the 101 page decision in Lorraine v. Markel American Insurance Company by Magistrate Judge Paul Grimm (one of the “rock star judges” mentioned in the ABA article), and the second is The Next Frontier: Admissibility of Electronic Evidence (Listrom, Harlan, Ferguson and Redis). (Note: this last link is on the ABA website and appears to require an ABA membership user name/password; as yet I am unable to locate a copy anywhere else).
