The stacks project is no longer an introductory text, but aims to build up enough basic algebraic geometry as foundations for algebraic stacks. This implies a good deal of theory on commutative algebra, schemes, varieties, algebraic spaces, has to be developed en route. |
| 2. | The stacks project has a maintainer (currently A.J. de Jong) who accepts changes etc. proposed by contributors. Although everyone is encourage to participate it is not a wiki. |

The stacks project is meant to be read online, and therefore we do not worry about length of the chapters, etc. Moreover, with hyperlinks it is possible to quickly browse through the chapters to find the lemmas, theorems, etc. that a given result depends on. |
