You "get your finger in the air" means to "go with the crowd", "go with the flow". You want to see, where the wind is coming from - usually by wetting the finger before. A person "putting his finger in the air" is unlikely to come up with original, individual ideas or solutions. And decisions are made unscientifically, without backing evidence.
In my experience, the phrase "put a finger in the air," used in a business and IT context, is another way of saying "make a high-level estimate." It's often an "order of magnitude" estimate (e.g., five or six figures; days/weeks/months), based on the speaker's experience or gut. It is another term for "SWAG" (Sophisticated Wild-Ass Guess). It does come from the practice of estimating the wind's direction by wetting one's finger and holding it up in the air.
Raising a finger in the air is sometimes seen as an outward manifestatation of an inward acknowledgment of GOD on a subliminal level. Not to be confused with submission to GOD or conformity to GOD, but rather a simple acknowledgement of the existence of. Sportsmen sometimes do this, namely soccer when scoring a goal a striker will raise a finger in the air, recognising Christ Jesus as GOD and the provider of the particular Goal and thanking him for the blessing of providence.
