The internet is what we make of it. Of course there has to be some realism about it (most services algorithmic by default etc), but I don't think it's enough to declare it's all over. Generally, yes, the internet has become worse, but some corners are growing, the 'small internet' especially-- if only in these small circles. Where you spend your time in really determines how you feel about this matter.

It's to be seen whether any remnants of the "old" internet come back to the mainstream though. I wouldn't know though, wasn't alive then. For anyone that was, what was it like?
