I was told that it’s great that there’s lots of links here. Links are kind of a chore, but an obsessive habit (from academic times). There’s some semi automation happening but the main downsides are:

1. Checking if they still work
2. Checking if relevancy hasn’t changed

The other con || pro (take your pick):

3. Friends more in the know, may dissect && tear you a new one when the content and the link disagree (with reality).

Insanely knowledgeable people are also out there online too. On occasion, when I bother with emails, I always end up learning extremely fascinating stuff.
