I don't think there is an overall tech bubble like 1999, but there may indeed be smaller scale bubbles in overheated or overhyped sectors.
There are two areas of worry from what I see. One is free apps and services with high burn and no good path to revenue. Another is what looks to me like a mini-bubble in startups that cater to other startups. Scene-centric inbreeding like that is probably more worrisome than the overvalued pic sharing services.
