IMO tech terms evolve a bit faster and are more accepted with their new spelling and meaning. Older words are less prone to such adjustments, but “alot” puzzles me as well.

Here are a few more to add to the confusion:

• From your own post, we now type “website” not “web site”
• We use email now, not e-mail, and definitely not “electronic mail”
• “Blog” is shortened “web log”
• Is it “username” or “user name”? They could mean different things, but might not
• It’s always “password”, not “pass word”. Same with “passphrase”.
• Is it “filename” or “file name”? In software, this becomes even more confusing since “filename” could imply a full path to the file, or just the name (sometimes without extension)
