I think making it version independent might be easier to wish for than to provide!
 
I believe the source code is available if you'd like to try getting it running on alternative infrastructure and updating it:

One thing I'd definitely support about this is making LSR somewhat version independent to allow one to have snippets requiring new lily versions.
Maybe providing several lily versions (not necessarily _all_ of course) and use an appropriate one to compile the snippets. This would also allow us to keep 'old' snippets without updating all to current lily syntax before being able to upgrade the whole LSR.
Maybe something like running convert-ly over all snippets when a new stable release comes out and leave snippets that can't be upgraded automatically for older versions?

PS: I'd also second the idea of hosting lilypond on a more accessible server (if that doesn't imply complicated side-effects). It is so easy to create a fork and open a pull request, I'm sure such a step would increase the number of contributions by people who can't or won't go through some undefined and possibly complex process of 'becoming a developer'

After some thinking, i came to the conclusion that LSR should be
redesigned.
Fristly, it should be a git repository, to make collaboration easy -
when something's a git repository, i have a habit of contributing
stuff there on every opportunity, because even if i do something wrong
i can undo this.

I'd guess you're in a minority of about 1% of users who would prefer using
git to using a web interface. The current web interface allows you to
copy-and-paste code directly in, or alternatively to type it directly in.
Both are simple and quick. To use git propoerly requires installing a new
program and learning how to use it. Remember yesterday when you recommended
a whole book about how it's used? If that doesn't put off casual
contributors, nothing will. I started work on LilyPond by adding regtests
to the LSR. If git had been required, I wouldn't have done so.

A valid concern, but i have a counterargument: there is a web
interface for git that allows you to copy-and-paste code directly in,
or alternatively to type it directly in. Both are quite simple and
quick. This doesn't require installing a new program and learning how
to use it.

It's github.

I've just checked and made a couple commits using that web interface.
Plain and simple, *with* all the advantages of git underneath. Of
course i may be biased, so i invite you to check this with me. I
believe that i will be able to explain everything that's needed in
5-10 minutes. Would you like to try?

Actually, i believe that it would be good to have lilypond repository
on github, so that new contributors would be able to create patches
easily. They wouldn't have to install a virtual machine with Lilydev.
Found a typo in documentation? Create a fix and submit it in *2
minutes.*

Secondly, i think that it shouldn't depend on any particular lilypond
version - in fact, it shouldn't actually run any lilypond in my
opinion. I believe that LSR should hold both snippets' code and their
output, with lilypond version clearly stated, and thus allow to post
snippets for any lilypond version. It would just be a collection of
snippets.

The benefit of it running LilyPond is that it shows the result of the code
on the fly - no need to create and upload images. This is another
significant benefit.

I'm not sure if i understand. Does LSR compile snippets every time i
open its webpage?
Anyway, i'm not saying that LSR shouldn't be able to run LilyPond,
just that it should not require this for operation.

I could elaborate on this topic, but as i don't have time to actually
do something about it it probably wouln't make sense (unless someone
wanted to lead such a change - then i would gladly help).

It doesn't need much changing - the main problem is maintaining the web
site.

What if the things i pointed out make it hard to maintain?
I'd just like to point this out:
- with current system, i know that i'm not going to help with updating
LSR. If i had more time, i'd gladly do that, but i don't have.
However, if it was independent from LilyPond version - i.e. updating
one snippet means that the update becomes instantly visible, because
updating isn't an all-or-nothing deal - i would gladly update some
snippets from time to time, if it could be done "via git".
- i have some valuable snippets and templates myself, and i'd like to
share them, but i don't see how they could fit with current LSR
system.
- i have 79 emails marked "valuable snippet". Adding them to LSR (the
way it works currently) would require a lot of work, and i don't have
time for this. But if the LSR worked another way, i could do
something about it.

If you'd like to discuss this more, i think IRC could be a good idea
(it's faster) - i'm logged in.

best,
Janek
