I wish there was a bit more information to be honest. Is this a patching system? Or is it just like an alert system for updates? I'm not really sure what it is.
Somehow I've signed myself up for a bunch of newsletters from various companies whose services I don't even use that update me on new features they've implemented in addition to blogs from their employees. It's an interesting read from time to time so I haven't unsubscribed.
If you can provide a service which can guide other people through publishing the same type of useful/interesting/insightful information regardless of the size/scope/nature of their project/research/work/business/hobby...
This idea is actually really exciting the more I think about it. Keep at it!
But the landing page needs more information, yes.
Integration with customer SSO, to provide different info for prospect/trial/paying customers or customers with different verticals/needs similar to the marketing landing page concept
My absolute biggest pet peeve with changelog emails is that they just say "Hey I'm Tony from Initech and we just added a new feature to BigBoomBlaster!!". I'm sorry who is Tony, why do I care, why did I care when I signed up for this list, what does this product do? What is an Initech?
I sign up to a lot of things, I need that taster of information to remember which of the 30 things I signed up to this week is emailing me without a hint as to who they are. No the domain name doesn't count, I didn't even read it when I signed up. The product already got me hooked enough to sign up for this thing, just remind me what it is and I'm all ears.
