I would. Depending on the quality of their Hubs and profile information. I am surpirsed though, how many Hubbers are answering here they wouldn't, having nothing more but a profile picture in disguise, not making it able to see your 'real face'.
A flower, a dog, a pig or whatever picture. It seems to me, those who have pictures like these without showing their 'real self', can't be expecting a 'real face' of a fellow Hubber. If that's what you prefer, why don't do the same?
