Yep, if you look in the top-right or bottom-middle of this page, you’ll note two Twitter links.
I know about it. This is intentional.
One links to @ilinamorato, my personal/family/geekiness/faith account. I’ve had it for a while.
The other one links to @RDavidAtwell, my work/professional/marketing/programming account. I made it shortly before getting business cards as a Salesforce employee, when I realized that my personal account just doesn’t look very professional. Heck, I tweet fart jokes sometimes. So I made a more professional account.
Anyway, yes, there are two Twitter accounts. That’s not a mistake.
(Well, it was at least intentional. Verdict is still out about whether or not it’s a mistake.)
