We use MapBox maps around the site

We suggest events based on the user’s Twitter

and LinkedIn contacts, and their interests

Each event has a page showing who is speaking and attending, the schedule and more

Speakers get detailed profile pages

Users can track topics in specific geographical regions

The site is built around a place hierarchy

So you can see everything in a specific city,or everything in England

Or view events for a topic in a place

Our microformats provide rich site snippets on Google

We provide GeoRSS feeds,which can be fed in to Google Maps

Our hierarchical place databaseis built on top of Yahoo! Geo Planet

We run off our own copy of the GeoPlanet database,which Yahoo! no longer provide...

But it has been mirrored by the Internet Archive

You can explore GeoPlanet using Yahoo!’s YQL API

treebeard is an excellent library for dealing with trees in a SQL database

Our search feature is built on top of Solr...

We support search within an area by indexingthe full place hierarchy for each event

Events have a primary venue, so we canplot them as a single point on a map

We encourage people to attach existing venues first to help avoid duplicates

Lanyrd has a foursquare app,which provides event informationwhen you check in to the venue

We have a tool to help match our venues to foursquare venues

Foursquare have an API specifically for matching venues

The apps platform is very powerful,and extremely easy to integrate with
