Been watching threads like this for awhile now and do not post very often. But Keith made a few comments that I’d like to respond to, as a User and a program manager for simulation software.
Specifically, to Keith’s comment, “I don’t see the point of posting 'we’re still working on it. every month.” and the follow up regarding the constant influx of emails asking when it will be ready.
First, the OP is right on one point…the ship really has sailed regarding the development of an iOS version and peoples expectations. the influx of emails you referred to and threads such as this confirm it. You stated you don’t see the point in posting progress to your users. This is probably because you are neck-deep in the development process, know exactly whats going on and have no way to understand why all these people just can’t wait for it to release.
Well, lets put you in their shoes for a bit. Lets say you hand off development of iScrivener and have no involvement in the process. Lets say days, weeks and months go by without any updates what-so-ever. As a PM, I’d be livid and looking for a replacement. I can’t not know whats going on with my software, i own it damn it!
But that’s us, the developer and manager of a project. We’re paying for the work that’s being done and are entitled to news.
What you may or may not understand, is that for many of your users, Scrivener is a kind of club. Its an amazing program for writing and not as many people know about it who should. So like being the cool kids at the concert of the band no one has heard of but soon will, they have a chip on their shoulder about it. “Have you heard of this program, its way better than Word, you have to try it.” …“Bitches, please…I’ve been using scrivener for years, BEFORE it was trendy.” They have taken almost cult-like ownership of it. I see it anytime I speak to other writers when I say I started using scrivener…some of them suddenly look at me like I am finally human. its really bizarre.
Are they entitled to do this…certainly not. But is it really in your best interest to shut them down? Like it or not, you are the head of a cult! A subculture revolving around writing software. Maybe you didn’t wanna be, but you are…your fans have taken ownership of your program without your permission…kind of like Star Wars fans. Maybe you don’t understand their needs for updates, but I think it really spills into the desire to feel ‘Involved’ in the development process of this tool they have come to claim.
My lame advice, for whatever its worth, is to go ahead and post a monthly blog on what yal are up to, tell some fun development anecdotes, show a few screenshots, all with the caveat that its WIP and subject to change. At no point will you say when its going to release, just show what yal are up to…keep your cult involved, don’t over hype it, don’t deflate it, just maintain it. I’d bet that the influx of mail will fall off, as will posts like this. You would actually spend less time addressing the issue and more time where its needed…in development.
While this may sound like a waste of time to you, and given that it does nothing towards development, I can understand why you’d think that. But it is 2 things for you…a bit of marketing…and two, the amount of effort you spend in forums posting on threads just like this probably equals more time than the blog would take you. Now, you have something to point your iOS fans towards:
“Where are we, what we’re doing, Ugg, you won’t believe what happened this month, etc etc.”
Hell, you might even come to enjoy sharing the experience with your worshipers
