Using the location field in Twitter accounts, we try to approximate the geographic location of up to 5,000 users and map them for you. This is an inexact procedure and so some points may be mapped incorrectly.

Our influence score is our proprietary rating of a user's influence and engagement on Twitter. It ranges from 0 to 100, where higher scores generally indicate a person with greater influential activity on Twitter.

Based on an analysis of users' profile data, when applicable and available, we guess their gender.

We've analyzed those whom SarahPalinUSA follows and assembled this chart to show you the number of people who follow those users. This is a useful way to pinpoint those users with the most followers (and therefore clout).

Here we highlight the following counts of those whom SarahPalinUSA follows. Generally, this is a less useful metric than the follower count (above). That said, we've found that people who follow a large number of users are often less "valuable" than those who follow fewer – this is because those people who follow a lot are less likely to comprehensively read their Twitter stream.

The age of an account is an interesting way to measure value. Users who have been on Twitter for a while are early adopters, and generally more valuable than newbies. As well, there is a higher percentage of spam accounts in newer user segments (as Twitter has not yet cleared them out).

If a person hasn't tweeted recently, then their account may be dormant. These data are based on the date that Followerwonk last checked the user, so the dates may not be entirely precise, but they should give you a good idea of who is tweeting more recently than others. Protected accounts are excluded from this analysis.

If a user has a low total tweet count, they may not be a "real" user. Perhaps they tried Twitter and gave it up? On the other hand, those with a very large number of tweets might be avoided (they could be spammers, overwrought, or just too verbose!)

This reveals the breakdown of languages of whom SarahPalinUSA follows. It's worth noting that Twitter only allows users to pick between a few languages (English, Spanish, Turkish, Italian, Korean, French, Russian, German, and Japanese). As well, many Twitter users who tweet primarily in a foreign language may still have their official language set to English.

This chart provides a percentage breakdown of Twitter activity by hour of day for the analyzed users. We chart in Universal Co-ordinated Time (UTC) (also known as Greenwich Mean Time (GMT)). Hover over each column to see your local time.

To help make sense of the "biography" field of each Twitter user, we've assembled this word cloud which shows you the most frequently occuring words.

Similar to the above word cloud, here we show you the relative frequency of words used in the "location" field of whom SarahPalinUSA follows.
