If I were doing a Target blog, here's how I'd start out:
1) I'd go to Feedster and search on "Target." (Actually I'd get an RSS News Aggregator first, and do a Pubsub search and subscribe to it). Nah, that search brings back too much noise and not enough information. So, do this search. Target +store. That brought back a little bit better info.
2) Then I would just start reading anyone who has anything to say about Target.
Suburban misfit: to the mother at Target today.
Jenny Solberg: Target Angst.
Glenn: (Not) Finding Neverland.
Wall Street Diva: "Target" Revelations.

Now, that's just in the past few days. It took me less than an hour to find all these links. So, now you have the raw material.
What to do now? Well, now I would link to them and react to the points. To the people who were disappointed in Target, I'd see if there is anything I could do to get them back into the store and fix their experience. To the people who were already thrilled, I'd just link to them and say "thanks." Or, something fun to let them know that Target saw their compliment and appreciated it.
What would you do with this raw material? How would a big company reacting to it change the perception of Target in the marketplace?
