I've made one proposal, then was unavailable to participate - the discussion moved on to the second stage. I return to see what happened and how I can participate now...
First it is pretty damn hard to find my proposal :) Eventually, by looking at the page for the specific question, bringing up the voting table, scrolling down to my pseudonym, and clicking on my pseudonym in the table (which appears to do nothing but a refresh) - then scrolling way down to the bottom - I find my proposal.
Clicking on the full detail - there is a very nice full description of what happened and a very useful graph - which however lacks and visual clarity with regard to which my proposal was - the information appears to be there but it is very hard to see visually.
This brings me on to the main feedback - make more of the graphs. The graphs should be the primary form of navigation - not an end result to then interpret. To achieve this there needs to be some improvements in the visual components of the graphs, and some bug fixes, and navigation enhancements.
By the way where is the open source repo - I remember coming across is - but there is no link to it from the web site. There should be a link on every page to the wiki / issue tracker on GitHub or the equivalent?
The bugs I've spotted so far are the faulty links in the graphs to the issues - see
http://vilfredo.org/map/1#proposal2398 There are also no links from author nodes to author pages.
The design feature I feel needs most work is in the area of proposal icons. There are some easy fixes, and some things that I believe we should go into in some more detail elsewhere. The problem is that currently it is impossible to view and track proposals across graphs as one blue square looks just like any other - this may make the graph easier on the eye in terms of clutter - but at the cost of meaning. We want to see what happens to a particular proposal first and only secondarily the overall argument. An easy fix would be to apply a randomly assigned blue colour to each proposal which would allow me to have a much better guess as to what happened to proposal 2398 - relying on me to be able to see the small text of the number, or having to blow the graph up to full screen does not work.
These are my first impressions - very promising, and a few quick fixes there that would dramatically enhance the user experience.
Also a note on process - you've also posted about open source methodology. I'll take a read - looks good from a technical perspective. It looks weak on the design issues with regard to the history or tools, community and open source. I feel it is more important that Vilfredo understand the soft aspects of community buidling espeacially how this relates to design, over the hard aspects of open source in terms of code.
With that in mind - the comments I make about design issues and bugs, should be dealt with through a process - and not ad-hoc. The process should be a process relevant to design - so it is not a good idea to use Vilfredo, nor is it a good idea to rely on the existing community as I suspect design is not a strong point. I'd recommend looking closely at user centred design, focus groups, mood boards, design sprints, and only afterwards look at what you code, and how you engage an open source community, and version control in the software development?
