Hey I'm one of the co-founders. Thanks for checking it out and for the comments! Right now the site doesn't filter for concentrated portfolios and we'll certainly be adding that. This is our first version of the product. Glad you noticed that! You might find more value in finding people who hold something you hold or something you're considering investing in.

We just added the "professional investors" section today and will be sure to work on the UX. Agree with your points here. That feature would be awesome, we're adding it to the list.
