Keep up with the latest research in Computer Science

So other than what the others have said, which I think is pretty reasonable (weird unattributed quotes and no about page, etc).

What you should maybe do is show content. If you don't have the userbase filled with tens of people ready to sing your praises, or you don't really want to put aside time to think up copy for extra about/contact pages, at least give the user a glimpse as to why they can't live without the service

You could have like an 'editor's weekly pick' of like 4 or 5 articles, that you think a lot of people are interested in, and give a preview of what your browsing features (or at least what the articles) look like. Then, people have a reason to want to sign up, right?

<Personal opinion> No example, no About page, anonymous subjective quotes,... Less superlatives and more details would make it look more like a genuine service and less like a scam.

I would like to sign up for this service, but I am unwilling to until it shows me examples of what emails I will receive.

The quotes on the home page don't have a closing quotation mark, and are not attributed to any people.
