Joins a 'party' with a ratio of 4~5 men to every woman (being very kind with that ratio btw), and boils his entire worth down to one page profile, that can be easily looked over and ignored.
Wonders why women don't respond.
Not to judge your lifestyle choices mate but honestly, with any given women I feel your chances are better served had you encountered her in real life compared to over a dating site.
Even if they do somehow see your message, it's like a few seconds of reading then deleted and ignored as she carries on with her life. She is likely to remember you more if you see her in real life, and put a living breathing face to the name. it'll feel more natural, the full spectrum and impact of flirtation, chemistry and interaction comes into play.
Basically humans have evolved, and our predecessor species before that to interact face to face in person.
If you can't use facial expressions, body language and all that to entice attraction and gauge potential, then how can you expect her to honestly take you seriously with just one message?
That is why online dating fails. The fact that there are legions of men fighting over a precious few women on them just makes the whole affair even more futile.
