Haha, not advertising per se. I think the better word that I'm looking for is... networking? I just follow them, join in tags (which we link to each others blogs and stuff so new comers can find us), like their posts (vice versa), talk/hang out online, volunteer to promote their works, beta read (and point out inconsistencies in their prose/plotline)... I know, that's a lot
And it's great because they help me out a lot too. Long story short, I'm a children's writer, and when I started my official writer's blog back in March, I worked on building connections with other writers (some, I've been following for the past couple years. Others are new faces that I've met during the networking phase.) I should leave my web link in my profile actually (been meaning to do that, but I keep forgetting lol.)
