I’m nowhere near as organized as Ignatius, so I just keep a few favorites that I know also have good lists of favorites themselves and/or tend to be very proactive in finding new data.
So for example deepseanews is a great ocean blog that has amazing content and a few great authors posting to it, but if I just want to see cool critters I’ve got RealMonstrosities, and he’s obviously really into what he does, and as a bonus he has links to Bogleech, (The biology section has some amazing articles!), Alex Wild’s Myrmecos (he makes ants cool!) and The Featured Creature (and Carly’s probably the most prolific of the bunch)
And they have links to follow that are sometimes neat, and the busy ones seem to update their own favorites more often as some blogs stop and others pick up. You end up in some pretty amazing crannies out there!
But I only had to keep the two handy.
