I have seen some users on meta having a "regular post", series or feature that they do.
My question is: how much reputation should you have before starting one?

The minimum required rep for creating a series of Meta posts such as "Know Your Site Monday" is the same as the required rep for creating an individual Meta post. In other words, there's no specific rep requirement for it. Nor is there a "soft limit" below which your series will simply be disregarded.
If you want to commit to something like that, though, you need to ensure you have:
3 is the make-or-breaker. I don't know why kingledion stopped doing Know Your Site Monday but I'm willing to bet it was 3. I have two stories with a regular schedule (one weekly, one monthly) and I'm currently severely behind on both due to lack of motivation.
So to summarise: you can start a Meta series right this minute, but you have to be prepared to commit to it.
You are asking about series of questions, the difference being series on Meta, such as kingledion's Know your site Monday series, and single posts on Meta with a list of questions on the Main Site like TrEs-2b's Anatomically Correct Series.
The latter is usually a collection of links about closely related topics, often framed in a similar way. Posting a Meta Post to collect them is a way to make the list easier for others to find. For example Anatomically Correct posts that want to be part of the series are encouraged to post a little link to the Meta Post in the question to give people interested in the topic a way to check out the whole series from different authors. See also Creating a realistic world Series for another example.
There has been some discussion about this concept. Look for example at Where can I post a Reference List? where our mods James and MichaelKjörling explained that they do not think this is a good practice. Look through the discussions to get a better feeling, but the gist of it seems to be that the community is a bit split nowadays when it comes to these collections. If you have a lot of questions set in the same universe and you would like to do more than just link each one to the previous one you could think about creating a Meta Post to collect them. Whether or not that is a good idea is probably a case-by-case decision. Some work well (like Anatomically Correct, which has been around a while) and some do not, like JDługosz' My “Alien Message” series that also links to posts on other sites.
The second thing is the Know your site Monday series, which is (was?) a regular series of posts on Meta with (in my opinion) interesting information about the site. It's useful to have this information on Meta for those who are interested in getting information about the site and how to obtain such information through SEDE, while at the same time making it a little game of sorts.
Looking through the posts there was always a bit of downvoting involved. I assume that's because Meta is not supposed to be for games, but for discussions and the information should be given without waiting and be geared towards a specific goal. There was not a lot of discussion about the merit of the series as far as I am aware.
Personally I would say that you can think about creating a series of your own under the following conditions:
You should not create a series when:
Reputation should not play any role in all of this.
