I propose that Tent entities be allowed to have multiple profile websites (Meta posts' profile.website). Having a single URL for one's self is essentially a relic of social media v 1.0 (Facebook, Twitter, forums, etc.), and, as I understand it, Tent's goal is to move the web beyond the confines of the closed-source systems that only allowed one website to be linked.
Having a single website isn't something that people who are "technically savvy", or whatever you want to call it, enough to have websites do anymore--they have a blog, a personal page, a portfolio, a company website, and so on. As it stands on just about every social networking sit, they have to pick a single one to post--that's not really fair, as they're usually all important to the person.
So, we should be able to either have multiple profile.websites, or have it be an array. Additionally, having a title for each entry might be good, so they can describe what the website is.
Do note it's a lot harder to create a UI to display multiple links or titles than it is to simply have a single link. The UI for this on a desktop site could be a hidden area that has a button to reveal it, sliding the rest of the UI down. Alternatively, on mobile, there could either be a dedicated page (probably the simplest thing to do with a regular app), a drop down, or a scroll bar area.
