How many articles are allowed in a newspaper?
How many topics are allowed in a talkshow?
The answer is simple: if you are able to produce 100 QUALITY articles, each day, for a longterm base...post it.
So if you have today 100 unique QUALITY article, post it TODAY, tomorrow the next 80? Fine, POST it... there is NO limit.
I have now idea, why some people say 1-3 or some like that and you also didn't run into a filter, if you post today 100 and tomorrow 50 BUT don't forget to have a PERFECT internal structure of your site. More content > links > better internal structure need, that anyone also find your QUALITY posts...
