Yes, I put my shop name on some of my listing (got a dozen or so that does), just so someone who searches for my shop can find me. I actually had "veniciacreations" as a search term in my stats quite a few times now!
ETA: But with the new "feature", it's much less required. When you search an item in the search box and get results, at the end of the first page, Etsy asks you if you want to "search shop names" with that keyword..So if someone searches "veniciacreations" and I had no tags, I think they could still find me easily.
