It could mean any of many things!
And clearly several can be true at once.
- I thoroughly agree with what you said!
- Hi - nice to see you but no time to chat
- I'm recc'ing your tip jar to show appreciation for the diary, but I'm not recc'ing the diary because it's already been on the Rec list for two days
- I don't agree with what you've said, but you make a clear and civil case for it
- You made a sincere apology for something
- I've read your reply to my comment
- You're a civil guest in my diary
Ah, but what if I don't recommend your comment? What does that mean?
- I'm not around right now - possibly biking, possibly scrubbing out the toilet. Something that involves muscles and tendons.
- The diary has so many comments that I didn't get down that far
- I visited the diary before you wrote your comment
- You made a great point, but you closed it with an insult
- I disagree with what you've said but for any of many reasons choose not to reply to it
- I'm on a mobile device and not recc'ing many comments
