To be honest "There’s no glamorous future for Mailmanagr, as well." pretty much sums up this article. It may be a good product, but its aim is not to be a high growth start-up and technically its just a component to an existing app.
Yes, it is just a component to an existing app, but it's a component that customers seem to want, and that the original app's developer didn't seem interested in building (but who can ever tell with 37signals).
Nope, just a guy explaining why he chose to market his Basecamp specific web-app via 37signals. Dur.
Best place for a start-up lesson? Probably not.
Should you not target techcrunch, even if your app would most likely not get covered, in order to maintain the exclusive nature of your launch? Sure, if you got a good plan B.
What?! Over half of Techcrunch-covered "businesses" are not even that: useless weekend projects without use nor future. By the way, I got an email from a co-worker today about Mailmanagr with subject "Check this out, it's pretty cool".
Last time I got an email like that was about Google's "Street View" feature.
P.S. I am not affiliated with Mailmanagr in any way.
I go to mashable for "weekend apps".
Of course, they have a lot love affair with Twitter and Arringtons ego.
At $5/month per user is a very low margin thats only reaching a market based on another non-mainstream apps userbase. This would definitely be considered a side project that regardless of TC is not very ambitious or PR worthy.
