I joined App.net ($5/month or $36/year) about five months ago. Although it's fundamentally a messaging infrastructure it's currently marketed as an ad-free social network.
I paid $50 at launch, and my account was extended when the cost dropped. That was money well spent; I expect to subscribe as long as they are in business. I love App.net because ...
- It has a very robust ecosystem of tools and services including multiple Mac and iOS clients and multiple web apps. I use Wedge, Netbot, NoodleApp and Appnetizen and will soon try Felix. There are multiple integration points to my Pinboard feed, including IFTTT support. Most of my posts start with Reeder.app [1] then go to Pinboard and turn into App.net posts via IFTTT.
- The community I interact with on app.net is exceptional. More on that below.
- I love the mission: a public (pay) communications infrastructure and related services that I purchase. I love paying for things I use.
- The app.net development team is delightful. I mean that literally; it's a joy to see them play and build on the platform - like @duerig's early stage Google Reader Share alternative, Patter-app rooms and private messages (EdChat) and vidcast shared video commentary.
- 128 characters is stupid. 256 is not twice as good, it's eight times better. (Though URL characters count, so I use URL shortener services)
- I'm 50+ and this is a relatively young community (though plenty of 40+ too). I'm old enough to enjoy that. The only young people I otherwise interact with are my kids (10-15) and their friends.
- I have the (illusion) of helping build something good without, you know, actually having to do anything. (Hence the illusion bit.)
- No advertising. Of course that doesn't mean no marketing; it means I choose the marketing I want)
[1] Alas Reeder.app may have been sunset. It's very unstable on the iPhone 5. Fortunately there are alternatives I can explore.
