Ohmigawd the new Etsy "Suggested Shops" feature is going to punch puppies and lock your grandmother in a cage! All the "Suggested Shops" on my list have tons of sales! Etsy is trying to widen the classist divide between the haves (sales) and the have nots!
When other sites' algorithms suggest books and movies, the more popular movies will show up more often on more people's lists, because by their very nature of being more popular, more people have read/seen them and liked them so they have more crossover with other books/movies that more people have seen, etc. etc. etc.
Go look through your own favorite shops. Odds are (and I really mean ODDS are, as in statistically more likely) the majority those shops have way more sales than 1) the average Etsy shop 2) you.
It's not because you value sales when choosing a shop to like, it's because shops that have made it across your screen and into your hearts are making it across other people's screens and into their mailboxes.
It's not evil or suspicious, it's human nature and Stats 101.
Go send promo packages to the big-name bloggers and get yourself more hearts.
