In the attached image, my favorite logos are 6, 21 and 24. Some of the others I like as well but these 3 stand out as the best style/look to me. Please ask me any questions you want, I want to give as much information to help create a logo that I will be happy with.
In addition to being blue and gold (more gold than yellow but see which combo of both works best in your eyes), perhaps there can be a small touch of green and/or possibly purple. For instance, if you were to go with the style of 24 and incorporate a tree, perhaps some green there for the leaves. I've asked a bunch of people about these logos and some like 24, others thing any kind of tree or brain image is too common and doesn't stand out. Honestly, I'm not sure how I feel on that, I can see the point but on the other hand, I think it can look very nice as well.
All the heart stuff I'm generally opposed to but something subtle like 6, that I can appreciate, but not like 2. Remember that, although the organization is about promoting both love AND knowledge, in practical purposes, it'll mostly be about knowledge. Therefore, I want the look to be more serious and professional to give us a more credible/trustworthy appearance as a reliable news/information source, vs. a more emotional type of image like a heart.
These are the majority of my thoughts on the subject but don't let that stop you from thinking outside the box and perhaps showing something totally different than what you see here.
