There is nothing as good as been rewarded for active participation and meaning contribution to the forum. However, newbie who may not be considered a newbie after ranking up tends to go astray.
After ranking up to member rank, the desire to engage in signature begin to grow after discovering or having known how signature works. Hey this is not to scare you away from signature but I do really think, the quest to meet up with numbers of post tends to lead many to low quality posting.
If poor quality posts are as results of members trying to meet up their post counts then this accuse should not be hold personally on the newbies but members who has been admitted to signature campaigns.
Although I would quite agree with you that some members are due to meeting up their post counts tends to produce low quality posts
Don't assume to have known much just because you have rank up, but exercise patience to learn well and be more useful to the forum, this will also help you have more quality post than chasing cloud.
Here in ranking up is a significant that your knowledge is growing and your quality contributions to the forum is the determinant of your ranking up through which your posts were able to earn you merits while activity counts is automated by your post counts.
You might actually know much but impossible to know it all and that is why even the high ranked members of the forum do ask questions and carrying on consultational researches in the forum for clarity at where they are complicated or have no knowledge about.
