I'm just checking on what has been done already at #Pixelfed and I'm thoroughly impressed. The web interface is already must better than the #Instagram interface. (Last I checked, there is none in Insta)
I love how you can search a Mastodon hashtag within Pixelfed, and it will digest all of the images of the Fediverse with that hashtag and make it beautiful.
That being said, the Android app is still in Beta, and I was not able to get logged in using that. But I'm really looking forward to it!
