20 years of Google Scholar

Yes, Google deserves to be distrusted and avoided as a whole, but Google Scholar is a genuinely net good for humanity.

I have similar feeing for Gmail (it's effective anti spam engine), google maps and google docs (which pioneered shared docs. It feels outdated on many fronts now, but it was a pioneer).

Most of the spam I get is from gmail. Maybe they should apply their so effective spam engine to outgoing mail as well...

It's probably not. You can put any domain you want on the "from" address. Just because it says it was from Gmail doesn't mean it actually was, unless it's signed with DKIM etc.

I had a domain for a while that people got spam "from" all the time. It had nothing to do with me and there was nothing I could do about it.
