Question

Is the commandment of publicizing the miracle dependent specifically on lighting the candles in the proper halakhic way?
For example, on this night when we lit one candle and a shamash, someone looking at them will not necessarily know which is the Hanukkah candle and which is the shamash. (When there are more candles, it is noticeable that one candle is at a different height or position from the others, but with the first candle that is not apparent.) And if the observer gets it wrong, could one say that the person who lit did not publicize the miracle properly and therefore did not fulfill the obligation through the lighting?
Is simply lighting candles anywhere that people commonly pass by considered the commandment of publicizing the miracle?
If that is indeed so, and publicizing the miracle does not depend on fulfillment of the commandment but is a commandment in its own right, is there then also a commandment to publicize it in other ways, such as on social media, status updates, street notices, and advertisements in the media? And if so, can this be stretched a bit further and say that one could fulfill the commandment of Hanukkah candles by means of WhatsApp, for example?
On the other hand, the lighting itself depends on publicizing the miracle, since if one lit above twenty cubits, one has not fulfilled the obligation.
