I used RIF for nearly a decade. Thanks for a great little app that got regular updates over the years. Talklittle, you are a great human! I will happily pay for your next app.
I have really been enjoying Comic Strips. There can be some political content, but there's plenty of other interesting and funny stuff too.
Rather than trying to replace something else, it's a good idea to look for what's new to you.
