So if I download or get sent "Book.pdf", I'll rename it to how I'll remember it -- "Book Title - Author.pdf", etc.
That being said, I don't think there's any right answer here, it's usually just a matter of time and energy. If I had to enrich every single file I download with a great title / detailed metadata / etc that I'd need to find that file later, that's all I'd do all day.
(otherwise I wouldn't have to ask a question about this topic if files I download had some title you'd easily find in a search through files)
and I was wondering if we should encourage people to utilize a certain filename convention or if existing lack of a convention has a purpose
(programming languages for example sometimes have "style conventions" for how code should look; likewise I guess this is a kind of question about a convention about naming files - intuitively I'd think a PDF file of a book on "Geology 101" should be named "Geology101Book.pdf" for example, but frequently I do not encounter this)
