Excellent post by Ryan from Fool about risky tech shares like 1PG and RFN. Especially the following points:

"... 105 tech company floats on the ASX in the last two years, with 45% of those businesses having had revenue of less than $1 million."

"Of course, many investors know the risks involved when buying the shares. If the product never takes off, there is the potential to lose 100% of invested capital. However, others are more naïve; they see a company with a promising product or service whose share price is soaring higher, and buy its shares only to watch them collapse again."

"It’s too early to tell whether 1-Page and Reffind will succeed in the future. If they do, current shareholders could be very well rewarded. But they are packed full of risk and the longer they go without generating a reasonable amount of cash, the less likely they are to succeed as investments."
