| That's a lot of sites out there and I thank everyone for bringing them to my attention. I'll be sure to pass them on to people who visit my company for more "tech" solutions.
But the argument that there is too much competition isn't an argument. Competition is healthy and yes, while there is a lot out there, that doesn't mean it's all useful or good. People use what's comfortable and, for lack of better word, good. Feedburner vs Google Reader, Gmail vs Hotmail vs Yahoo, Thunderbird vs Outlook vs Apple Mail, etc. Some of them seem very nice and I'm sure they're quite flexible in giving you what you need.
I'll be doing a bit more research over the next few weeks to see building it with all the "availability" options as suggested like txt messaging, cell phone apps, etc is worth the time and money. Or if I can convince my company to do it. |
