It seems like you're suggesting mainstream news sources are somehow different? Personally I prefer the explicit bias of individuals on Twitter, than the implicit bias of mainstream news sources.
Mainstream media's bias is no more implicit than that of many individuals on Twitter (e.g. celebrities) and at least my time is better spent reading about a subject on selected media that span a wide political spectrum. But there is a risk: you might get the impression that mainstream media reporting is disturbingly inaccurate, on all sides.
