Yes it very much depends on the queue size and moderator workload around their real life commitments.
As far as frontpage exposure goes, don't worry about it. In terms of readership and engagement it makes very (very) little difference. Hardly anybody besides bots camp on the front page. Their job is to index content and see how busy the site is so they can come back more regularly. They also index the category pages, which have far more stories on them - with more relevance to the category itself - and spend longer on page 1 of the respective results.
My competition piece has been on the front page for over a month and has gained about a hundred views and 1 like/comment in that time. Same for all the comp pieces, this time and last time.
Cultivate your readers. Engage with them. Read and comment on other works. Drum up interest in the forums and your profile wall, and encourage followers to check their reading queue regularly.
When we get a more focused page for all our friends and followers, that will help even more. But until then, focus your efforts in places other than the front page, as those will reap greater dividends.
