I'm using them as I would conversationally. Commas might be more appropriate but saying their placement doesn't make sense is silly. They're obvious pauses if I were saying g this aloud.
Jesus guys, I was on the mobile site and ellipses are faster when I'm already feeling limited by my thumb's tapping ability to have to go hunt for the comma. I didn't realize it was such an issue that it spawned 6 comments about my style and zero comments about the content of my post or the article.
I mean, do I explicitly need to write: "I'm so sorry, I know I should have used commas but I didn't and it wasn't easy for me to proof-read on my device"? Good lord, even the original post is being crucified without response.
