Now I was quite confident this would happen, because of a mechanism I like to call:
"The disadvantage of the dominant product"

[4.6498]

[4.4233383]

Now I was quite confident this would happen, because of a mechanism that is called
"the law of the handicap of a head start".
(or in Dutch "de wet van de remmende voorsprong").
This term was coined by Dutch historian Jan Romein in his essay "The dialectics of progress" in 1937.

The dominant product will get a lot of attention.
Both positive *and* negative.
Your product - or the users of your product - could be popular victims of malicious software
(This is the reason why there are so many viruses on Windows, compared to Linux for example)
Also, if more people know your product, then in theory there are more people that can come up with fresh new ideas that your product doesn't have.

[4.4233384]

[4.50862]

The law suggests that individuals or groups that start out ahead eventually are overtaken by others.
In the terminology of the law, the head start, which is an advantage at first, subsequently becomes a handicap.
This phenomenon occurs when a society dedicates itself to certain standards and those standards change.
Then it becomes harder for the leading group to adapt.
This is exactly what happened during the browser wars!
Society demanded tabbed browsing and Microsoft had a hard time adapting to that, which resulted in Firefox and Chrome taking over.

Though the SourceForge implementation is a bit unorthodox.
Because Fossil needs just an SQLite database to generate static HTML.

It was even written specifically to support development of SQLite.
