Is it possible to build a chat/(group chat) app on top of lightning network?

For what purpose? I don't think it's needed if you are thinking it's needed for discussion & learning or even getting help. Because, you can learn everything here in the forum. A lot of legendary are here to help you and figure out if any problem you face to. I have recently had some discussion on Lightning Network and it's my pleasure that I have learnt a lot from the forum.
By the way, a beginners guide to learn basic about Lightning Network if anyone is interested- https://bitcointalk.org/index.php?topic=5202798.0

It'll be pretty interesting - imagine being able to talk to people in a way where you can't be controlled, and then also being able to send payments via the same messaging system, it'll be a sorta, super platform, in very simple man terms.

I'm not sure about the DDOS threat to it though, wouldn't it be pretty hard for someone to do, unless they had a lot, a lot of power?

The lightning network can actually do a lot of stuff, not just send and receive payments in a fast manner.

That's another similar service. But have to wait for the invite.

Just to be clear... Do you want some chat feature built into the Lightning Network software to enable LN Hubs to talk to each other or do you want

a chat application like Whatsapp or WeChat that incorporates the Lightning Network as a internal currency with some kind of plugin? There is need

for both of these applications, but the one for a large Social media platform would be better for Bitcoin adoption.    I think these companies would

create their own Crypto currency, because they would want to control all aspects of it.    You cannot add a currency feature and then rely on

external influences to determine the future of that technology.

People need the chat feature built into the Lightning Network software to enable LN Hubs to talk to each other.
The world needs a fully noncustodial chat software build on the Lightning network.
This will truly protect privacy.
