Newsletterest now supports the topic feature

Another weekend job is done!
Newsletterest now supports the reader to browse and subscribe to a topic containing a list of related newsletters.

Some examples:
Best newsletters about Mobile App Development: https://newsletterest.com/topic/1016/Mobile-App Development

Best tech newsletters https://newsletterest.com/topic/3/Tech-News

I hope that is an easier way to subscribe to favorite newsletters.
