Yes, time is also relevant of course. But almost everything is still written down, so the time difference is more included in the two first points.
And yes, priorities do change quite often. Some things are important at a certain time. For example we released the Live map to ride on the Road Trip '15, wich our special filters. I imagine it was a good entry level for many new users.
Then there is a lot of time spent on support, understanding the issues and bug fixing.
Also not everything is relevant. This week I corrected an error with the book keeping. I have known about it for a while, but didn't know why it happened. But this week I finally fixed the error, and then I had to develop a program to create the vouchers for those that didn't have any.
In the beginning of the year there were new VAT rules within EU, regarding electronic sales. I probably spent over a week on adjusting to that. Understanding it. Calling Skatteverket (Swedish tax people). Discussing with other business owners and the one doing the book keeping.
Then there are all the maintenance. Upgrading of servers and their software. Most of these things don't fit to have public, and they are quite often the reason to why it seems like nothing is happening for a month.
I would like to get new things out there almost daily and write at least 3 news letters every month. But right now, that doesn't seem possible.
