# Possibilities
---
* Geo-analysis with [available](http://censusreporter.org/) [open data](https://www.opendataphilly.org)
- True on-the-fly rendering as map markers (JS is hard)
* [Lexical research](http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0073791)
- gender, age
- psychological characteristics

<section data-markdown>
# Caveats
---
* Estimated only 1% of tweets have location
* Emoji meaning vs. use
* Inconsistent rendering across platforms
