Just a note to say that if you are using Matrix and want your conversations to be indexed in search engine ("Google-searchable"), you can deploy matrix-static[1] or you can use the live instance hosted by the Matrix foundation[2].

I think an interesting comparison, for both Linen and Matrix, would be to compare these 2 approaches: Linen natively indexed conversation and this Matrix "static" client. I would be especially interested by what additional features Linen provides in term of indexing compared to this static client.
