thanks @tuckpuck - sounds interesting, looking forward to checking it out - in the meantime, I would recommend a "zoom in" on your image: considering that the thumbnail image is only about 280px wide and the text wouldn't be readable.

Resolved all questions from #1456 (review) ... except the image zoom-in which can be done at the contributor's discretion.

Thanks all for the approvals and feedback! Appreciate it.

I think the zoom level is fine for now, the heading and subheading is still visible. I plan to change the home page at some point soon anyway, at which point I will submit an updated image with the latest.
