Here’s my approach: over the holidays I suggested lemmy to 3 people I know. I did so by emailing or texting them links to the following piefed feeds of lemmy communities:

• https://piefed.social/f/highsignal
• https://piefed.social/f/highmemecontent

The first is non-political, non-tech, low-meme communities (tho sometimes those topics sneak in.) The second is non-political, non-tech meme/humor communities. One peson said they thought it was neat, the other said they bookmarked it, the third didn’t say anything. Dunno if they joined.
