- More censored.
- More commercialized.
- Less open, more walled-gardened.
- More banal (For example, academics used to write long Usenet posts, then they started to write blogs, now they mostly bicker on twitter)
- Less sincere and personal, now people mostly use it as just another PR tool.If you dont conform, you will be cancelled, downvoted,banned, etc.
Now, before someone comes to accuse me of "Old-man-yelling-at-the-clouds syndrome", I fully accept that in absolute terms we have more good things now, but the signal/noise ratio is also a very important thing, or as papa Stalin used to say: "Quantity has a quality on its own" , for every thoughtful post,blog,site we are drowned in thousands of crappy sites and it is not always very easy to distinguish them, because it is the sad reality that quality publications will little by little become crap just to survive or fit-in.
