The Internet as we all know is a hype machine.  With all the tech blogs and pundits out there, it is hard to really know what sites/companies are gonna make it over the long haul.  What I would like to know from everyone, is what companies you have heard about in the last few months that you think are going to make it in the long term and why you think that.  Please be specific, since we don’t just want the answer, “Facebook Apps”.  Also, please give specific examples of sites or ideas even if it is not a new company.
