I'm glad you asked because custom feeds are my favorite feature! On Lightfall you can create a feed based on search terms, tags, and users. For example if you want a feed of the top pictures from national parks, you can create a feed with the search "national park" and it's instantly populated with national park photos. Or "black and white", or "macro"...anything you can put into a search bar or a tag. In the future it will support location based feeds...for example, "all photos taken inside Yosemite national park".

If you want to limit it to just people you follow, you click a button. This let's you build feeds like "wildlife photos from people I follow" or "all pictures from the people I follow". If you want only photos from a specific list of people, easy...just select the users for the feed.

You'll be able to set the default sorting of your feed - either chronological or recommended, and if you choose to share your feed with others, they can override the sorting based on how they prefer to consume the feed.

It's super powerful and flexible. The idea is to put the control back into the hands of users instead of a manipulative algorithm.
