When there are a large number of spaces to select from, the space selector page becomes unwieldy (see screenshot below):

• Cards require scanning in a left to right, top to bottom, zig-zag fashion which makes it difficult to compare spaces
• Cards are large with a lot of empty space, which limits the amount of information on screen for scanning and comparison
• Wasted space to the left and right of the cards

Some information that's also missing from this:

• Name of space creator
• Date the space was created (helpful for identifying recently created spaces)
• Date the space was last accessed by the logged-in user

I think a designer could take a couple passes to optimize this page for a couple use cases:

• Helping the user visually acquire spaces that they tend to use most often
• Helping the user visually acquire spaces that they've recently created
• Helping the user sort, search, and filter spaces

My suggestion would be to split this view into two levels: a primary level consisting of cards for the user's last 5 or 6 most recently used spaces, and a secondary level consisting of a table ordered by newest spaces to oldest.
