Why should I care about lightweight vs. annotated tags?

Question

I switched from Subversion to Git as my day-to-day VCS last year and am still trying to grasp the finer points of \"Git-think\".

The one which has been bothering me

Answer 1

Annotated tags store extra metadata such as author name, release notes, tag-message, and date as full objects in the Git database. All this data is important for a public release of your project.

Lightweight tags are the simplest way to add a tag to your git repository because they store only the hash of the commit they refer to. They can act like "bookmarks" to a commit, as such, they are great for private use.

You can sort, list, delete, show and edit old tags. All these functions will help you to identify specific release versions of your code. I found this article that could help you to get a better idea what tags can do.
