Yeah, it does kinda feel like the profile pages gets forgot. I hear on mobile devices they're kinda hard to get to? However, I do like looking through the "thanks for subscribing posts". Sometimes creators will write special messages along with the image. It's also how I find a lot of unknown comics on Tapastic. I try to encourage creators to post their "Thank yous" to my profile instead of private messaging me the "Thank yous", because I like to help promote other comics where ever and whenever I can. 
But yeah, I completely agree. It'd be nice if they were more of a Facebook like profile where people were comfortable enough to talk and hang out on them....ponders.... However, I know some comics where they do that on the comic pages themselves, and that actually helps out the comic series more. The more comments, shares, likes a comic has the better chance of getting featured. So comics that have long chains of comments are actually in a better position to make front page. That might be why the profile page is kind not used for that...hmmm...
But either way, sure I'd like to be your friend on Tapastic
I've been following your comic since the beginning, and I love the sprite animations you have for the game so far. XD
