Just in time for me to cite in something I've been using GlobDB for
Our paper describing the GlobDB is now published in @bioinfoadv.bsky.social

I feel this. A big part of my professional growth over the last few years has been the realization that I will not live to carry out the vast majority of my ideas. As a result, I'm much more open with sharing them than ever before.
Science is like this too 🧪
I am not aware of a single author who has a shortage of book ideas. Words, yes. Ways to make the ideas become a book, yes. But I've never met an author who doesn't have ideas just raining down all the damn time.
