I find most colors of the hashtags fine to read on my iPad and phone but challenging on my MacBook which is almost ten years old. But the hashtag ¡°stack¡± on the home page is pretty uncomfortable to look at and just appears to me as clutter. FWIW - I¡¯m older than dirt, have astigmatism and have medication-related vision changes.
