Okay, data time: I created a full-text-search bookmarking app called historious ( http://historio.us ). It started out as free for everyone, since I just built it for myself and people found it useful, but I quickly had to charge, after realizing that people had more than my 10-20 bookmarks (some people had 80 THOUSAND). I changed it to 2,000 free bookmarks, and unlimited paid, which worked well. Then I changed it to…
Thanks for providing an interesting data point. I had a few questions I was wondering if you might be able to answer ? 1. How did you deal with existing free users already exceeding your new limits ? (and how did they react) ? 2. Did you see a measurable increase in upgrades after doing this ? 3. Did you see a measurable decrease in free users of the service after doing this ? Thanks.
I have also needed to cull unused accounts (of free users who haven't logged in in months). This provided a great boost to the service (saved me from needing to keep upgrading the server for the past few months), but it has also produced a few false positives of people who hadn't used their accounts for a few months and came back. Luckily, I keep backups they can just restore.
2. The last limit change was a few days ago, so I haven't had a chance to gather significant data on this. I guess we'll know in a few months.
3. I will also track this, that is a good question. I anticipate that a few users will be deterred from using the service for free, but that might not necessarily be bad (I am not sure).
