1) How did you first learn about Omnimaga and what aspect influenced you to stay?
This took some digging. It looks like I found the site (or at the very least created an account) to talk about nspire development. This was in the days when installing ndless meant running the original OS version, with a certain power management bug that made your batteries drain really fast.
2) Do you feel as if we have similarities outside of programming naturally. If so, what are they? (i.e. MLP fans)
I don't think this counts for what you're asking, but there's the shared interest by many members in general electronics.
3) For what reason(s) do you frequent Omnimaga over other sites like Cemetech or TIPlanet? (Or vise-versa)
TI-Planet is french, and I don't speak french. Not much of a reason, I know.

Mostly, there's more activity on Omni and most of Cemetech maintains a semi-active presence to the point that being active on both sites only affects whether maybe 4-5 people see me. Omni also has a better layout imo.
4) Do you consider the community of Omnimaga to have a main goal(s)? (if so, what are they?)
I would say there are several factions of Omni with their own goals, and members generally belong to at least one. I will list them:
The programming faction, who use the calculator to fulfill their own purposes through programs.
subsets include:
The hacking faction. (Critor, thepenguin, etc) which focuses on making the calculator do what TI prevents.
The power faction. (Runer, calc84, etc) which focuses on making the calculator do things as well as possible
The gamer faction, which focuses on making entertainment-oriented programs. (Much of the community)
The helper faction, which focuses on making things for other people to use. (Axe, Grammer, the various IDEs, etc.)
The BASIC faction, which focuses on making programs entirely through the crippled built-in languages. (This includes Lua)
The MLP fans, whose sole purpose is to annoy me. (j/k)
5) How do you feel your relationship is with other members?
Lurker, mostly.
6) Do you find that Omnimaga (and calc programming) has helped you in the outside world?
Yes, occasionally. My programming experience has helped in many cases, for example.
7) What is your favorite inside joke/lingo? (i.e. Holy Necropost Batman! or Welcome peanuts etc.)
Netham, while a blue lobster, has a pink username.

What country are you from?
