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.

What is your “I don't care if this succeeds” project?
A torrent client that exposes torrent content as files: https://github.com/distribyted/distribyted
It's pretty fun to work on it and implement new use cases. Right now it supports FUSE mounts, but I'm thinking to make it work as a WebDAV server too.
Also, I'm working on several demos, like SQLite compatibility, similar to https://github.com/lmatteis/torrent-net, or CSV analysis using Jupyter notebooks for huge datasets like https://ghtorrent.org/

How to collaborate on web scraping?
Store the scrape progress (to-be-scraped / in-progress / scraped / in-error URLs) in a database shared by all participants and scrape in parallel with as many machines as the db load permits. Got a connection timeout / IP is blocked on one machine ? Update the scrape status for the corresponding URL and let another machine retry it. https://github.com/get-set-fetch/scraper (written in typescript) follows this idea. Using Terraform from a simple config file you can adjust the number of scraper instances to be deployed in cloud at startup and during the scraping process. In benchmarks a PostgreSQL server running on a DigitalOcean vm with 4vCPU, 8GB memory allows for ~2000 URLs to be scraped per second (synthetic data, no external traffic). From my own experience this is almost never the bottleneck. Obeying robots.txt crawl-delay will surely put you under this limit. Disclaimer: I'm the npm package author.

How to serve scrapped data?
Written in typescript https://github.com/get-set-fetch/scraper stores scraped content directly in a database (sqlite, mysql, postgresql). Each URL represents a Resource. You can implement your own IResourceStorage and define the exact db columns you need.

How to scrape entire blogs with content?
You can use https://github.com/get-set-fetch/scraper with a custom plugin based on the mozilla/readability as detailed in https://getsetfetch.org/node/custom-plugins.html (extracting news article content). I think it's a close match to your use case.

Web Scraping 101 with Python
I'm using this exact strategy to scrape content directly from DOM using APIs like document.querySelectorAll. You can use the same code in both headless browser clients like Puppeteer or Playwright and DOM clients like cheerio or jsdom (assuming you have a wrapper over document API). Depending on the way a web page was fetched (opened in a browser tab or fetched via nodejs http/https requests), ExtractHtmlContentPlugin, ExtractUrlsPlugin use different DOM wrappers (native, cheerio, jsdom) to scrape the content.

What is your “I don't care if this succeeds” project?
https://github.com/get-set-fetch/scraper - I've been working (intermittently :) ) on a nodejs or browser extension scraper for the last 3 years, see the other projects under the get-set-fetch umbrella. Putting a lot more effort lately as I really want to do those Alexa top 1 million analysis like top js libraries, certificate authorities and so on. A few weeks back I've posted on Show:HN as you can do basic/intermediate? scraping with it.
Not capable of handling 1 mil+ pages as it still limited to puppeteer or playwright. Working on adding cheerio/jsdom support right now.

puppeteer-cluster - Puppeteer Pool, run a cluster of instances in parallel
playwright-recaptcha-solver - ReCaptcha V2 solver for Playwright
playwright-python - Python version of the Playwright testing and automation library.
pyppeteer - Headless chrome/chromium automation library (unofficial port of puppeteer)
