I have to chime in. I know, I'm not exactly impartial, but hear me out.
Firstly, I hope that everyone giving up CathInfo is equally giving up other, much more frivolous websites. Facebook, CNN, any sites that feed off curiosity, etc.
Because CathInfo is *not* the worst website out there, or a bad habit that would benefit your life/health if it were permanently broken -- like sugar, caffeine, cigarettes, alcohol, etc.
CathInfo is many good things:
A source of Catholic news
A vital lifeline to keep in touch with what's going on in the SSPX
Edifying posts about the Faith, liturgy, saints, etc.
Infomative posts by our more educated and knowledgable members, on various topics of morality and the Faith
A vital connection to other Traditional Catholics -- who would otherwise be quite isolated, who might be "forced" to make friends with worldly people IRL instead
Humans are social animals. They NEED the interaction of other people. Only a few chosen souls have a vocation to the eremetic life (being a hermit). Even most religious don't have this calling. It takes a special grace from God to be able to totally isolate yourself and go without interaction with fellow human beings. Keep that in mind.
Just like a mother could be foolish to discourage her son's courtship of a young lady who attends the Indult. What if she succeeded, only to have him start "dating" a worldly Novus Ordo Catholic, or even a non-Catholic, out of desperation? It all depends on what the young man's other options are. If he could only scarcely find the Indult girlfriend, he should probably keep her.
Unless you attend a vibrant Traditional chapel with hundreds of people (St. Mary's, KS?), you might be causing undue isolation -- psychological stress -- by isolating yourself from other Catholics of your own age and state in life.
CathInfo could be used like Facebook, or it could be used as a vital lifeline to critical information about current events in the Church. I guess it depends on how you're using it at the moment.
How about this: For those of you giving up "CathInfo" for Lent, I want to ask you to do me a favor. One or two weeks into your abstention, perhaps you could ask yourself an honest question. "Is my spiritual life in better shape than it was before Lent started?" If the answer is yes, then by all means keep up the good work! If you've wasted more time on worse things, you might want to reconsider your Lenten resolution.
