I've always liked the original logo but I also I like and prefer Josh's new logo because of it's simplicity. As stated by others it remains easily recognizable even when scaled down, an important feature for compelling logos. I voted "Yes" for Josh's logo. Regarding the slogan, it's a step in the right direction, GRC needs a slogan. However, Gridcoin needs to reach a broader audience that may not be in the crypto world, or even be aware of Steem, etc. In my pursuit of exposing people to GRC they get glossy-eyed the first time they hear me say "cryptocurrency" and I know I've lost them at that point. Hence, I feel we should avoid "cryptocurrency" in the slogan. A slogan which simply states the end result, that Gridcoin helps people help science would pique people's interest without scaring them away.
