but in general, if google can’t read it–few eyeballs will ever see it.
You bring up a good point. The Internet is full of spider bots that crawl the web to index it and improve search results (ex: Google). In my case, I don’t want that any comment I post here or on big platforms like Reddit, Twitter or LinkedIn to be indexed. But I still want to be part of the conversation. At least I would like to have the choice wether or not any text I publish online is indexed.
