I am currently living in Seoul for short term and we are always talking about how this social segment is really missing outside of specific online community meetups.

Overall, I think this is really cool concept and on the right track. Currently, I would like to drill down first by Location/Region followed by interests and then have you show me who fits those two criteria. If there are too many matches I would refine/add more and if too few pull back on my interest selections.

Good luck on the project!
