So today iPhoto joined Picasa in adding face recognition to their package. I too wish that you prioritized this feature as it is a real time saver. As happens all too much in software development, you don't understand how we use your product.
I am a photo hobbyist but still have THOUSANDS of digitial photos spanning over a decade. As the technology has changed they have resided on cards, proprietary camera manufacturer software, MS picture folders, hard drives, NAS, iPhoto, Aperature, Picasa, Shutterbug, websites, Flickr with various formats. You must believe that the major challenge is manipulating photos when it is ORGANIZING them. Moving to LR rarely brings forward any keywording necessary for this task. So moving to your new package means days, if not weeks of PAINSTAKING re-org and tagging.
If you asked your users, what are you really trying to find in your library...I guarantee it would be a specific picture of a specific person at a specific location. FACE RECOGNITION AND GEOTAGGING are the key features for creating the data necessary to finding the photo. To me and my friends this seems like common sense. I do not need more PS capabilities in LR. I however do NEED more organization, workflow and data import/export capabilities. Split the work with Picasa, they have an open API and a pretty good search algorithm (sarcasm). They want to rule the air you want to rule the desktop so it seems an equitable marriage...
Okay I am starving...so my rant is over.
