+In layman's terms, the license says that you can take TiddlyWiki and do anything you want with it without any license fee payment or other legal obligation to the creators of TiddlyWiki or anyone else. The quid pro quo is that there is no warranty or guarantee with open source projects like TiddlyWiki. You can't sue the contributors to TiddlyWiki for any loss or damage due to the use of TiddlyWiki: even if your data is lost due to a tragic chain of circumstances that involves TiddlyWiki.

+You are respectfully requested that to make an attribution to the project, but there's no obligation to do so.

+For the avoidance of doubt, any information that you choose to store within your own copy of TiddlyWiki remains yours; using TiddlyWiki to publish content doesn't change whatever rights you may have to that content.

 People love using ~TiddlyWiki. Because it can be used without any complicated server infrastructure, and because it is [[open source|OpenSource]], it has bought unprecedented freedom to everyone to keep their precious information under their own control.

-TiddlyWeb is a server application that puts [[Tiddlers]] on the web:
+TiddlyWeb is a reference implementation for an interface to put [[Tiddlers]] on the web.
+
+It was created by a team led by Chris Dent at [[Osmosoft]] under [[BT]] from 2008 to 2012. 
 
 http://tiddlyweb.com/
 
 TiddlyWeb can be used to host TiddlyWiki and TiddlyWiki5 wikis, making the individual tiddlers available over a flexible HTTP API.
 
-TiddlyWeb was originally sponsored by [[Osmosoft]] at [[BT]] (along with TiddlySpace).
+Other implementations of the API include:
+
+* [[TiddlyWiki App Engine Server|https://github.com/rsc/tiddly]], a 300-line Go implementation from Russ Cox
+* [[TiddlyWiki 5 server module|https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/commands/server.js]], the bare-bones subset of the API implemented in TiddlyWiki version 5 for Node.js
+
+As of early 2017, none is currently as complete as TiddlyWeb itself.
