Hi LisaRose,
I prefer 'post 1, fave 10' activities because it helps get seen in activity feeds of those who follow the favers and leads to new followers. Following each other as well - although we are limited to 1080 - but by also liking the shop, we are still connected.
I also like shop of the day/week activities but admit I don't always have time to participate. We each post 1 item from the featured shop and 1 from our own, then like all before us (or even 10 or 20 items before would be fine).
I also like to connect on social media, so threads where we can share our outside links are good. Then we can have repin, retweet, or comment type activities. Just yesterday a site I had enjoyed using, Polyvore, was taken over and shut down. That could happen on other sites too, so being connected elsewhere helps.
Thank you!
