Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Looking for help getting started with TinyFPGA
apio is a python package you drive from the command line. I didn't know somebody had done an integration with Atom. I've installed and used apio on my phone. I wouldn't really recommend doing that, but it shows what's possible.

Learning Verilog and FPGA
I've had good experiences using Upduino 3.0 and 3.1 [0] with the IceStorm tools via apio [1]. I wrote a blog post [2] with some info on getting things set up via Linux. All you need is the Upduino board, which interfaces to your host system via USB (so no special programmer is needed).

FPGA dev board that's cheap, simple and supported by OSS toolchain
if you're more comfortable with the CLI, you should take a look at the apio project (https://github.com/FPGAwars/apio). It neatly bundles all the required tools. Regarding HDLs, I'm still learning so can't offer any good advice on that.
