Macy's solves the problem of coupon codes in a way that's good for everyone. They have a coupon code box. They also have a link to a page that shows you all available Macy's coupon's. If one applies to your cart, you can use it. If there isn't a coupon for your cart, you might find out something else is on sale and buy that too. If you don't care about coupons, you can check out and ignore the box.
It's trivial to filter out of office messages if you use a decent email program. The false positive rate should be as close to zero as you can get.
Reading every feedback email from every real user teaches you how to create better products. If you make it clear users can provide feedback, there's an opportunity from them.
I ask every single real person who leaves my service why they left, which translates to about 12 emails from me per week. Most of the time, the feedback isn't actionable, but 2-3 of every 50 emails translate to something I can use to make my product better.
Facebook is in the process of gradually rolling out sponsored search. I think businesses with big budgets get to cut to the front of the line.
What's curious to me is the difference between the Democrats and Republicans on this. The Romney campaign is clearly on the offensive as well as playing smart defense. If you search for Paul Ryan, you see Romney as the top result. If you search for Bill Clinton, either Ryan or Romney show up. The Obama campaign does not appear to be bidding on any terms.
Since when does trusting a business critical function to a free service make any sense? At least GoDaddy has a motivation to provide some level of service because people are paying them.
I use the latter one and in addition to providing an alternative to my registrar, they also seem to have much faster response times, which cut some milliseconds off a site lookup.
My suggestion makes sense since they are a very big ISP and they simply don't care about the cost of a service that they would need to provide to their clients anyway.
Namecheap does the same and most people think that they provide a good service.
Seriously, pay if you want, but if you aren't Google, you don't need to pay for reliable DNS hosting.
Like Onavo before them, Wajam is using the Profiles feature of iOS to add a layer of functionality that's impossible to accomplish by building a standard app. The question is, how smart is that?
If we start training users that they should click on links in email to add features to their phone are we opening up an opportunity for man-in-the-middle type attacks or other unwanted behavoir?
I should also say, I'm not suggesting the Profile feature is bad in general - I've found it invaluable for using with things like TestFlight, but as a general distribution case, it seems like something to be discouraged.
