Activity level

[kailuowang]

In regards to project activity, I would argue that Cats is significantly more active. I have two reasons to believe that:

1. Cats, as a much younger project, now has 183 contributors, vs 157 contributors for Scalaz
2. You used prev month commits as a metric, but Cats is mostly doing squash PR merge, meaning for most PRs merged we have only 1 commit/PR while Scalaz might have more than one commits per PR. If you look at the PR merged here is the data:

month	Cats	ScalaZ
Last 30 days	32	16
Oct	43	11
Sept	42	14

*My count might be 1 to 2 off. But the ratio between the two should be roughly the same.

I hadn't realized until I did this PR that you guys do squash merges. I'll admit that that should change the way we perceive activity.

I was expecting something similar with respect to project activity by highlighting the release activity.

I've collected some of that data to help get it going.

Release	Year
Scalaz 6.0	2011
Scalaz 7.0	2012
Scalaz 7.1	2014
Scalaz 7.2	2015
eff 1.0	2016
cats 0.6	2016
cats 0.7	2016
cats 0.8	2016
eff 2.0	2016
cats 0.9	2017
eff 3.0	2017
eff 4.0	2017
cats-effect 0.3	2017
cats-effect 0.4	2017
cats 1.0	2017
cats-effect 0.5	2017
eff 5.0	2017

I'm unsure of whether Typelevel packages like cats-mtl, fs2, mouse and so on should be included.

Some aggregate numbers may be more digestable for users. "Release frequency" or something, perhaps rendered with a chart.

I am going to close this issue since there isn't much point of keeping it open.

After thinking about it again, activity level is hard to measure (or qualify) and might not be useful. Project activity is correlated to project health/quality, but strictly does not cause it. So, I'm okay with this issue being closed.
