Hi Martin, thanks for the feedback :)

Specifically which aspects of the mockup do you think are
debian-archive-expert-oriented? (I feel exactly the same way and was
trying to ensure it was welcoming to new PPA publishers).

So, if I'm understanding you correctly, you are saying that it is not
enough that they can view currently building packages etc. at
+ppa/my_ppa/packages to see that info but it should be part of their PPA
summary - yes, good point.

Actually, even including the (paginated) packages at the bottom of the
page may not be sufficient (unless the initial ordering ensured that
recent uploads appeared at the top).

This *might* be the perfect thing for a side-bar portlet - recent
actions on this object (there are some pretty strict guidelines about
what can and can't appear in the 3-0 sidebar):

Firefox-3.5 (5 mins ago)
  [building-icon] currently building <-- link to build record with
version details etc)
Thunderbird-xy (2 days ago)
  [fully-built icon] Fully built

BTW: I'm currently in the process of creating permanent wiki pages for
key LP pages describing the use-cases and target audiences. I've just
drafted:

https://dev.launchpad.net/SoyuzPPAIndexPage

with the information you provided - feel free to update it of course if
I've mis-represented your points!

That is a very good point and flaw that I hadn't thought about. Hmm.

Yes - I'll have to re-think the content there. As you say, most popular
packages does not really make sense at all in the context of a software
channel.

Yes, so the new mock has the description first, and my thought was that
the most popular/recent packages would also help make that decision, but
as you've pointed out they don't. Perhaps the install instructions
should follow - or some other information which helps make the decision
(I'm starting to get the feeling that something summarising the scope of
the PPA is most relevant - as I mentioned in my reply to Max on lp-users).

Did you notice that with Karmic you won't need to do that? That is, mvo
has done the work so that we can just add 'ppa:username/ppaname' to
software sources and it automatically imports the key? But sure, we
could include the sudo command in the 'Technical details about this PPA'
drop-down (which should be perhaps 'Manual instructions for adding this
PPA' or something similar.

I don't think the stats are the type of information that fits the
guidelines for the 3-0 sidebar (actionables, subscriptions etc.), but
will find out more soon.

Hmm... I'm not sure if you're referring to the image of the current PPA
page, or of the mock that I suggested. I've got a comment at the bottom
of the mock saying that if the viewer is the owner (or a member of the
owning team, or an admin - which i forgot to mention) then they will see
two extra portlets in the main area, "Build status summary" and
Repository disk usage. So if we did that, normal users wouldn't even see
the repository disk usage.

Hmm... while I think the list of packages should stay there at the
bottom for the moment (I'll include it in the next mock), I am hoping
that we can find a better way to communicate the scope of the PPA
without so much detail. Something like:

For ppas with <= 5 packages:
This PPA will currently only update the following packages on your system:
  * one
  * ..

For ppas with > 5 packages, we'd just refer to the complete table.

Off topic, but it would be *great* to be able to say "This PPA only
updates the following packages on your system (you will be notified if
further packages are added in the future)." - ie. have some concept of
PPA scope built into PPAs and controlled by owners.

Yes, agreed.

So thanks Martin for the valuable feedback - I'll go back and try again
with the mock based on this (and any further feedback).
