Twitter Pulse #fsharp 2014

Past two years, at the beginning of the year, I did a post where I have tried to sum up year results and find some interesting facts/stats from tweets:

This year was really awesome, a lot of things happened:

There are so many things occurred, so I need your help to find everything that happened or changed this year.

Especially for this, I prepared a data set with tweets starting from Jan 1, 2013 that is available here, and ask you to help me analyze it.

How to start:

  1. Download  the data set & unzip an archive.
  2. Download latest version of Fsharp.Data.
  3. Copy-paste following code snippet:
#r @"..\packages\FSharp.Data.2.1.1\lib\net40\FSharp.Data.dll"
open FSharp.Data

type Tweets = CsvProvider<"fsharp_2013-2014.csv">
let tweets = Tweets.GetSample()

//TODO: Your awesome analytics here

My sample analysis:

As an example of what you can do with data, I prepared a calculation of people activity that shows who had more tweets this year.

tweets.Rows
|> Seq.filter (fun x -> x.CreatedDate.Year = 2014)
|> Seq.groupBy (fun x -> x.FromUserScreenName)
|> Seq.map (fun (group, items) ->
    (group, Seq.length items))
|> Seq.sortBy (fun (_, cnt) -> -cnt)
|> Seq.take 100
|> Seq.iter (fun (group, cnt) ->
    printfn "%s:%d" group cnt)

When you execute these rows you will get a statistical output in FSI with user names and number of tweets. You can copy this output to wordle.net and play with settings to visualize it in the nice way:
2015-01-02_1007

Please help me to observe data set and share your results with me on Twitter (@sergey-tihon). I will include your plots/charts in the end of this post. Thank you!
