i didn't bother to vote cuz i had no idea -- looking at that little box in the middle of the screen -- cuz i was too distracted by the lousy user interface and the lack of context.
however, i did cut and paste the url to look at your site and to answer your question, it depends. this is a corporate blog. it has to serve some purpose other than a cool place for ios-aficionados to hang out. and you have to consider, do you want genuine feedback from your users; do you want them to engage; and are you prepared to listen to and act on opinions you (as a company) may not share or want to hear. cuz it not, don't go there. you'll be opening up a big can of worms.
