developers are operating directly on the master branch, or at most
a small number of well defined branches.  
The [concepts.wiki#workflow | autosync] mode of Fossil makes it easy
for multiple developers to work on a single branch and maintain
linear development on that branch and avoid needless forking
and merging.

<h3>3.3 Branches</h3>

Git (and especially GitHub) encourages a workflow where each developer 
has his or her own branch or branches.  Developers then send "pull requests"
to have their changes be merged into "official" branches by integrators.
For example, the Linux kernel team has a hierarchy of integrators with
Linus Torvalds at the root.  Individual developers each have their own
private branches of the source tree into which they make their own changes.
They then encourage first-tier integrators to pull those changes.  The
first-tier integrators merge together changes from multiple contributors
then try to get second-tier integrators to pull their branches.  The
changes merge up the the hierarchy until (hopefully) they are pulled into 
"Linus's branch", at which time they become part of the "official" Linux.

In Git, each branch is "owned" by the person who creates it and works
on it.  The owner might pull changes from others, but the owner is always
in control of the branch.  Branches are developer-centric.


Fossil, on the other hand, encourages a workflow where branches are 
associated with features or releases, not individual developers.
All developers share all branches in common, and two
or more developers can and often do intersperse commits onto the same branch.
Branches do not belong to individuals.  All branches are read/write
accessible to all developers at all times.  There is no need
for integrators to merge together changes from various independent
developers.  Instead, all of the developers work together cooperatively
and the changes stay integrated naturally.













So to a first approximation, branches in Git are developer-centric whereas
branches in Fossil are feature-centric.


The Git approach scales much better for large projects like the Linux


kernel with thousands of contributors who in many cases don't even know
each others names.  The integrators serve a gatekeeper role to help keep
undesirable code out of the official Linux source tree.  On the other hand, 
not many projects are as big or as loosely organized as the Linux kernel.
Most project, have a small team of developers who all know each other
well and trust each other, and who enjoy working together collaboratively
without the overhead and hierarchy of integrators.

<h3>3.4 Complexity</h3>

Git is a complex system.  It can be tricky to use and requires a fair
amount of knowledge and experience to master.  Fossil strives to be
a much simpler system that can be learned and mastered much more quickly.
Fossil strives to have fewer "gotchas" and quirks that can trip up a
