First off its great to see her back on YouTube (good luck with her show on the Dash channel)
Q1
Does she have any other presenting work lined up or is she exclusive to Dash now?
Q2
Does she blog or write articles? If so, where can we read her stuff? It would be great if she posted to Steemit, I'm sure it would get lots of upvotes ($$$!)
You can read her "contract" details here - https://www.dashwhale.org/p/dash-youtube-show - I dont think it makes her exclusuve to Dash, but conflicts of interest will most likely be frowned upon by masternode voting party.
She wrote this recently.

I'd hope the dash community would take the broad view on Amanda's participation in the wider crypto space. The more she's seen as a respected sage and advocate for crypto generally the better it reflects on them (given she's nailed her colours to their mast, so to speak).
I can speak for myself in that i wouldnt mind her doing work for other projects. Shes a great spokesperson for the industry as a whole.
