Slurp seems to be late to the party and overhypes their dismal 'solution' as an all encompassing panacea. Many have a love-mostly hate relationship with IM clients in the office as they a source of easy harassment when having to send an email or horrors actually walk to the person's desk would be more appropriate. The worst abuse is when one is going through their morning hate mail to see what is causing their hind quarters to burn and some pings with a question about an email just as you begin to read them. I have them ask about something that was assigned to me overnight which I had not even had a chance to review with expectation that I could give an intelligent answer about it. Teams just another moronic excuse to needlessly harass people and cause a drop in productivity.
