In my opinion as an outsider (and one that uses a normal keyboard and doubles up on keys just like you do) many comments here are genuinely trying to be helpful. You’re asking for a layout that fits your current typing habits and based on their knowledge and experience they’re telling you that you might want to drop that habit instead. That’s advice and you’re not obligated to take it. It seems to me that you’re misinterpreting a lot of those comments as criticism.
Millennial here. I’ve been consuming Reddit, and now Lemmy, almost exclusively on my phone and for me it’s card view all the way. Often the graphic content is more important than the title and opening posts only to find out it’s not funny or interesting feels like a waste of time. Only when I find a post interesting enough that I want to comment or see the comments, I open it. Instances or communities that I don’t like go on the blocklist.
If I really need to use Reddit, I open old Reddit in the browser with an extension that turns it into a mobile friendly site with card view. The new design has always felt sluggish and bloated to me, but not because of the card view.
