Technically, yes, but at least it's not filter bubbling everyone.
While still somewhat detrimental, it's at least a visible problem - everyone is aware of it because everyone sees the same thing.
With filter bubbles, you create personalized echo chambers, that nobody is aware of unless they're in there.
This is social media. It's a fairly benign manifestation of it, I suppose, but it's social media nonetheless.
Something to consider while carefully crafting denigrations of what we all think is meant when discussing "social media." Especially if you'd rather not see HN and similar places damaged by righteous politicians.
