I've been rooting for you and recall enjoying the blog posts about its making - I've always figured that "RSS is dead" and there is no longer money in clients (people used to pay for desktop readers!)..
Except that Google would kill Reader eventually and somebody will soak that userbase of nerds right up. And NewsBlur is clearly the top choice and will hopefully occupy similar mindshare as Reader did for us until now. Congrats, well played. :)
I wonder what the next one along these lines will be as now would be a great time to start building it.
That said I do think that going after markets abandoned by the big guys is an excellent way to go. Usually they abandon it because its not a billion dollar business and isn't worth their time.
I believe now that you need to start attacking their market-share before they close the product down and use the closure as a marketing opportunity.

Also some quick, simple advice:
1. Blog 2/3 times per week minimum. Target a single, relevant keyword per blog post (relevant to your domain). The post title, H1s, H2s etc, image tags should all contain your primary keyword. Blog posts don't have to be long, but they do have to be useful.
2. Build a G+, FB, Twitter account for your site if you haven't already. Blast out your new posts to these accounts using Hootsuite (free, but you can pay if you like).
3. Build an audience on the social networks - just search around, follow relevant people and share useful, educational material. Don't spam.
4. Personalised mass email from Google Docs and Gmail (kind of hesitant to recommend this in light of Google shuttering services!): http://www.labnol.org/internet/personalized-mail-merge-in-gm... you need to have "newsletter" signs ups (blast out a digest of your blog posts once per month), calls to actions etc on your site for this to work properly (i.e. optimise your site to capture names & emails). Great, low cost/free way to make sure your audience stays engaged and coming back to your site. You can pay for this kind of service too, e.g. Mailchimp (they've a free tier), Constant Contact, or the likes of Hubspot for full suite of marketing automation tools.

Many engineers don't fully appreciate marketing as patio11 would be quick to point out, but there's a start.
That kind of thing is never going to help

Not pretty but have some real examples. Please post your own and paste a link here or in the comments.
Now is too late. The right time to have started building it was 2-6 months ago. Now is the time to market an existing solution.
Citing the great gretzky quote, the "puck" is already here.
I mean-- err, yes, totally too late! Don't worry about it.
We've been working on it for the past few months.
With backstitch (http://backstit.ch) we get questioned a lot why Google is no longer supporting these types of services (and if this means there is no opportunity there since they aren't worried about it anymore). We honestly feel like there is a lot of surface left uncovered when it comes to personalized/streamlined content and it just doesn't seem to be part of Google's refocusing (this has been seen with the shutting down of a lot of their lab projects as well).
In my industry merchant accounts are very difficult to come by. We are considered high risk. Even with a year of processing records showing 1 chargeback out of >3k transactions I can't get access to a merchant with decent rates(currently paying 3.7%). All the big players turn us away. There's gold to be mined off the beaten path.
