I am all in favor of side projects but I found a number of disturbing errors:

* There are no conferences for either Ruby or Elixir * There are no conferences on bitcoin * There is only one conference for React * You can leave data in the form on where by not picking autocomplete and then it appears to have searched for it but gives incorrect results * The only way to clear the date settings is to reload the page

I love the concept and the lack of knowing what conferences are happening even nearby is a very real problem but I think there are issues with your database and your search interface.
