In my "Sparks" feature, I write about things I dig. For today's Sparks, I present three Web sites on astrology that rock my Casbah.
I've been using AstroAdvice for a decade, easily, if not longer. Register for a free account and learn a helluva lot about yourself. Use the "Romance Compatibility" section to get a rating of your particular attachment as well as pretty danged accurate interpretations of how you and your honey's planetary aspects have y'all relating to one another.
You register at AstroDienst to get in depth analyses of your psyche as well. My fave feature of this site is the Free Daily Horoscope, which seeks out the most important planetary action in your particular chart. They, like the above site, provide paid-for reports, but I find them both rather pricey. But the free stuff here, as well as on AstroAdvice, is pretty nifty. On Thursdays, you can read for free about other transits impacting your life (which, during the other days of the week, you need to be a member to see).
If having to register for free stuff pisses you off, you may want to check out Cafe Astrology, where you can also obtain very in-depth natal chart/romantic compatibility chart analyses, for free and without giving them identifying info on yourself (of course, you can use fake names for any/all of these). They also provide loads of other freebies, in terms of monthly/yearly 'scopes, broken down by decanates (check the site to learn more about these). Paid-for reports are also available here, and I've bought a few over the years, as they're way more affordable than others I've seen, plus I've found their interpretations to be pretty spot on.
And because I'm in an expansive frame of mind (must have some Jupiter transit going on), I'll give honorable mentions to Matrix Software's Oracle and e-Tarocchi, two other fun sites where you can easily while away your hours.
