I have to say I really don't like the curated browsing categories. It's just more of what Etsy staff thinks is "cool" to promote. My views have gone way down since they went away from the old categories on the front page (and also since the search was changed, though I try really hard to use good tags!). Valentines jewelry looks like a bunch of personalized stuff, stuff that may or may not have anything to do with Valentine's Day. I make what I think is tasteful heart jewelry, and I don't see mine nor anyone else's in there that is similar.
Sorry if I seem grumpy, I'm still frustrated after a very poor Christmas season, which is usually a really decent time for me on Etsy.
If anyone has any tips for getting found (besides all the Etsy articles which I have read and tried to follow), or insights into these curated or partially curated browsing categories, I'd love to hear!
